Understanding Ayurveda: A Way of Looking at Health

One of the things I find interesting about Ayurveda is that it doesn’t begin and end with the question of what is wrong with the body. It also asks what it means for the body to function well, what helps maintain that state, and how the way we live influences our health. This might seem like an obvious distinction, but it changes the way we approach the subject. We are accustomed to thinking about health in terms of symptoms, diagnoses, and treatments. Ayurveda, while certainly concerned with the treatment of disease, also places considerable emphasis on preserving health before illness develops. This is not a new idea in medicine, of course. But in Ayurveda, the maintenance of health is the very foundation of the system. The word Ayurveda comes from two Sanskrit words Ayus, meaning life or lifespan, and Veda, meaning knowledge. It is translated as the science of life. What I find significant about this definition is its breadth. Ayurveda is not concerned exclusively with disease or the human body as an isolated biological structure. It considers the conditions that support a life of health and well-being. To understand this approach, it helps to look at the principles on which Ayurveda is built. According to Ayurveda, the human being was never understood as entirely separate from nature. The body is made up of the same fundamental elements that exist in the world around us. The food we eat, the air we breathe, the water we drink, and the environment we live in are not external to our experience of health. They are constantly interacting with us. And perhaps this is why Ayurveda places so much importance on paying attention to the world around us. Our bodies do not exist in a vacuum. They respond to changes in temperature, seasons, food habits, activity, rest, and countless other things that we may not always notice. Of course, this doesn’t mean that every change in our health can be explained by our surroundings, or that we can resolve every problem by changing our lifestyle. But it does remind us that health is influenced by more than just the part of the body where a symptom appears. Another thing I find interesting is that Ayurveda doesn’t assume the same approach will work for everyone. We often look for universal solutions. The same diet, the same routine, the same supplement, the same advice, hoping that what worked for someone else will work just as well for us. Ayurveda encourages a more individualized way of looking at things. Two people might experience similar symptoms but have different underlying patterns, habits, and needs. Their constitutions, digestion, sleep, and responses to their environments may differ. So, while the symptom itself matters, understanding the person experiencing it matters too. This is where the classical concepts of Dosha, Dhatu, Mala, and Agni come into the picture. These are not simply terms to memorise or labels to assign to ourselves. They belong to a larger framework through which Ayurveda understands the functioning of the body. Each concept describes a different aspect of that functioning, but none of them can be understood entirely in isolation. And that, to me, is an important distinction. Learning a few Ayurvedic terms or identifying our Prakriti does not necessarily mean we understand Ayurveda. The concepts begin to make more sense when we understand how they relate to one another and how they fit into the broader principles of the system. The same applies to the way Ayurveda understands food and medicine. We often reduce a substance to a single quality: this food is good for you, that herb is beneficial, or this ingredient is something you should avoid. But Ayurveda considers several aspects when understanding how a substance may act on the body. Its taste, qualities, potency, and the changes it undergoes after digestion all contribute to that understanding. Some effects are also described as specific to a substance and not fully explained by those other properties alone. This is why simply memorizing that a particular herb is used for a particular condition can give us an incomplete understanding. The more interesting question is why it is used, in what context, and for whom. Ayurveda offers a way to think through these questions rather than treating every ingredient as though it has the same effect on every person. I also think it is worth paying attention to Ayurveda’s emphasis on prevention. A lot of our conversations around health begin only when something goes wrong. We look for a diagnosis, a treatment, or a way to get back to normal as quickly as possible. Ayurveda, however, also places importance on the ordinary things we do before illness develops: our daily habits, our relationship with food and rest, and the adjustments we make as our circumstances change. There is something quite practical about this idea. We may not be able to control every aspect of our health, but we can become more attentive to our habits and to the ways our bodies respond to them. Rather than following a routine simply because it is popular, we can begin by asking whether it suits our circumstances and whether it is actually helping us. At the same time, understanding Ayurveda does not mean accepting every traditional claim without question. Its concepts belong to a particular philosophical and medical tradition, and they should be understood in that context. Where claims concern the treatment or prevention of disease, they also need to be evaluated carefully against appropriate scientific evidence. Respecting a tradition and examining its claims critically are not mutually exclusive. For me, the most useful way to approach Ayurveda is to look beyond the individual remedies, routines, and recommendations we encounter so often. Those things may introduce us to the subject, but they are only one part of it. The principles behind them are what help us understand how the… Continue reading Understanding Ayurveda: A Way of Looking at Health

Maybe It Is Not Just What You Eat, But How Much

We have become very good at asking what we should eat. What is the healthiest breakfast? Which oil should we use? Is rice better than roti? Should we have more protein? What should we eat for good digestion? There is always another food to add, remove, replace or worry about. But there is one much simpler question that often gets lost: how much are you actually eating? Ayurveda has been asking this question for a very long time. In the Matrashiteeya chapter of the Charaka Samhita, the discussion begins with something remarkably straightforward: matrashī syāt, essentially, one should eat in the right quantity. And then comes the important part that quantity is not exactly the same for everyone. It depends on the strength of one’s digestion. That immediately makes the conversation about food a little more interesting. Because we often speak about food as though the food itself is the whole story. We label something “light” or “heavy” and assume that its effect will be the same every time we eat it. But even foods considered naturally light or heavy still depend on quantity. Something that is generally easy to digest can become difficult when eaten in excess, while a heavier food may be manageable in an appropriate amount depending on the person’s digestive capacity. In other words, there is no point in asking only, “Is this food healthy?” without also asking, “Is this the right amount for me, at this time?” Eat according to the proper measure; the proper measure of food depends on the strength of digestion. It sounds almost obvious when you hear it, but think about how rarely we actually apply this idea. We eat because it is lunchtime even when we are not hungry. We continue eating because the food tastes good even after we are full. We finish everything on the plate because that is what we were taught to do. We order more because we are out with friends. Sometimes we eat very little all day and then compensate with a huge dinner because we are exhausted and starving. The food may not necessarily be the problem. Sometimes it is simply the relationship we have with quantity. The chapter makes another interesting distinction between foods that are naturally lighter and those that are naturally heavier. It mentions foods such as rice, green gram and certain meats among the lighter foods, while describing things such as preparations made from flour, sesame, black gram, milk and certain meats like fish as heavier. But even here, food is not reduced to a simple good-food versus bad-food list. It repeatedly brings the discussion back to quantity and digestive strength. This is important because the idea is not to become afraid of foods that are described as heavy. It is to understand that the same food can behave differently depending on how much of it you eat, how strong your digestion is and what else is happening in your body. You do not have to create a permanent list of foods you are “allowed” to eat and foods you are not. You can instead become more attentive to what happens after you eat. Do you feel comfortable? Does the meal digest without leaving you excessively heavy or sluggish? Are you hungry again at an appropriate time? Do you feel energised or do you feel like you need to lie down immediately? These observations are not meant to turn eating into another thing to obsess over. They are simply a way of becoming familiar with your own body. The appropriate quantity of food often supports one’s strength, complexion, comfort and longevity. That is quite different from the way we often talk about food today, where every meal can start to feel like a calculation of calories, protein, carbohydrates, fats and restrictions. Ayurveda’s concern here is much more functional: what does this food, in this amount, do to the person eating it? And it does not just stop with food. Health is maintained through small acts of care repeated regularly. Take something as ordinary as brushing the teeth. Your body is something you maintain, not something you only attend to when something goes wrong. We have a strange relationship with self-care today. We can spend hundreds of rupees on a product marketed as a “self-care essential” and still forget the basics. We can have a complicated skincare routine but sleep four hours. We can buy supplements while eating at completely irregular times. We can spend an hour researching the perfect shampoo and then ignore the fact that we are exhausted all week. Sometimes care becomes another form of consumption instead of something we actually practise. The Matrashiteeya chapter offers a much quieter idea of care. Eat in the right quantity. Keep yourself clean. Take care of the senses. Pay attention to the body. Maintain routines. Do things regularly rather than waiting until a problem becomes severe. There is a sense of maintenance rather than constant correction. And perhaps that is the part of this chapter that feels most relevant now. Eating when we are actually hungry. Stopping before we have eaten far beyond what we need. Paying attention to how a meal makes us feel instead of blindly following a food trend. Keeping our bodies clean. Taking a few minutes to care for our skin, hair, feet and senses. Giving the body enough rest. Building routines that are sustainable rather than impressive for a week. There is also something important in the way the chapter describes the body: almost as something that deserves regular attention and respect. Maybe that is what we miss when we reduce healthy living to individual foods and isolated habits. Because sometimes the most useful change is not finding a better food. It is learning when enough is enough. Health does not always come from… Continue reading Maybe It Is Not Just What You Eat, But How Much

Why Your Body Isn’t Just “Tissues and Waste”

Most people, the moment they start reading about Ayurveda, land on this word, Dosha, almost immediately. Vata, Pitta, Kapha. And usually, the very first explanation they get is something like “Dosha means fault” or “Dosha means fluid,” and honestly, that explanation doesn’t help at all. If anything, it makes the whole thing feel more confusing than before you started. So let’s actually slow down and ask a more basic question first. What is the body even made of, according to Ayurveda? Before we even get to Dosha, there are two other categories worth understanding, Dhatu and Mala, because once you see how these three relate to each other, Dosha suddenly makes a lot more sense. Dhatu refers to everything in your body that’s meant to stay. Your blood, muscles, fat, bones, the fluid in your spinal cord, reproductive tissue, all of it. These are structurally very different from each other, obviously, but they share one thing in common, none of them are meant to leave your body under normal circumstances. When they do leave, by injury or bleeding or some other accident, your body doesn’t feel relieved. It feels depleted, anxious and weak. That’s the signature of a Dhatu, its presence sustains you, and its loss destabilizes you. Mala is the exact opposite category. This is everything your body is meant to get rid of, stool, urine, sweat, and so on. And here’s the interesting part, getting rid of these isn’t a failure of the body, it’s actually a sign of it working properly. Holding onto waste for too long doesn’t protect you, it burdens you. A Mala that overstays starts creating problems rather than preventing them. So while Dhatu is defined by staying, Mala is defined by leaving, and both, in their own way, keep the body functioning. Now here’s where it gets genuinely interesting, because Dosha doesn’t fit into either of these categories. It refuses to follow the rule. Think about saliva for a second. It’s produced inside your body, moves through your salivary glands, briefly steps outside the boundary of your internal tissue system into your mouth, and then re-enters your body as you swallow it along with your food. It doesn’t stay put like a Dhatu, and it doesn’t fully leave like a Mala either. It does something in between, and that “in between” behavior is exactly what defines a Dosha. It moves out into contact with the world, and then brings something back in, and this back-and-forth movement is precisely what makes digestion, absorption, and basically your entire relationship with the outside environment possible. This is such an important shift in how to think about Vata, Pitta, and Kapha. They’re not things that cause or lead up to a disease. They’re the functional bridges that let your body interact with everything you eat, breathe, and absorb from the world around you. Vata handles movement, what you take in. Pitta governs transformation, converting of one thing into another. Kapha manages binding, lubrication, and the way things hold together and connect. Without these three doing their job constantly, your Dhatus would never get built, and your Malas would never get properly separated out and removed. And here’s something that genuinely surprised me the first time I really understood it, this dual-direction movement of the Doshas happens twice a day, in the gastrointestinal tract specifically. If something you’re consuming regularly doesn’t actually suit your body, that excess starts getting expressed back out, sometimes as an unusually sour or pungent sensation, sometimes as a sweet, sticky feeling. This isn’t randomness, it’s your body’s own feedback system, quietly telling you that whatever you keep feeding it in excess isn’t being absorbed the way you assume it is. Most of us just don’t know how to read that signal. This is also why identifying someone’s Prakriti, their natural constitutional dominance of one or two Doshas, matters so much in how Ayurveda actually treats a person. Two people can eat the exact same meal and metabolize it completely differently, purely because their underlying Dosha balance is different. What nourishes one person can genuinely unsettle another. This is the entire logic behind why Ayurveda has never really believed in one-size-fits-all diet advice, it was never really about the food. It was always about how well your Doshas are managing the exchange between what’s outside you and what needs to become a part of you. So the next time someone tells you Dosha simply means “fault,” it’s worth remembering that it’s actually closer to the opposite. It’s not what goes wrong in the body. It’s the very mechanism that allows the body to keep working, keep exchanging, and keep staying alive in the first place. If ideas like this interest you, our courses on Charaka Samhita and Ashtanga Hridayam go much deeper into how Dosha, Dhatu, and Mala work together as the foundation of the entire Ayurvedic system.

Ama: When Digestion Is Incomplete

After you have had your meal, there might be times when you feel heavy. It is not exactly tiredness, but you do not feel nourished either. Your head feels foggy, there is a discomfort you cannot quite ignore, and yet it is not severe enough to feel like something is seriously wrong. There may also be a feeling that you have not experienced complete satisfaction from the meal. It is almost as though something inside you is saying that the process is not finished, that the job has not been completed. Today, we are going to talk about one of the widely spoken-about concepts in Ayurveda: Ama. When the accumulation of Ama is greater, it can give rise to a condition described as Amadosha. To understand Ama, we have to go back to something we have spoken about before: Agni, our digestive fire. What Is Ama? Ashtanga Hridayam describes this state directly. When the digestive strength is low, the very first tissue formed from food, which remains undigested, becomes vitiated and gets lodged in the stomach as unprocessed matter. This is described as Ama. When Agni is working the way it should, the food we consume gets properly digested, absorbed, and converted into Rasa Dhatu, the first and most essential tissue our body produces after digestion. But when Agni is weak, this conversion does not happen cleanly. Your food is not entirely digested, but it is not entirely rejected either. Some of it remains half-processed, turning into something called Ama. Ama is not exactly food. It is not waste either. It is something caught in between the two, the result of incomplete digestion and improper transformation. What Causes Ama? One of the causes is eating more than what your hunger can accommodate. Ayurveda describes this as atimātrā āhāra, or consuming food in excessive quantity. When food is consumed in a quantity greater than what the digestive capacity can handle, it places a burden on Agni. This can lead to the aggravation of all three doshas and interfere with proper digestion. But it is not exactly about quantity alone. The nature of the food also matters. Food that is heavy, dry, or cold can contribute to the formation of ama, even when it is eaten in a reasonable amount. And it is not just about food. Your lifestyle, mental strain, and the mental state you carry throughout the day can also contribute. When your digestive capacity is compromised, even food that you consider light or harmless may not be processed properly. When Agni is weak, food does not necessarily provide the nourishment your body requires. Instead, according to the Ayurvedic understanding of ama, incompletely processed material can behave like a slow-acting poison within the body. What Happens When Ama Interacts With the Doshas? As this undigested or improperly processed material interacts with the doshas, its effects can vary depending on how the body responds. It may become trapped and cause a condition described in Ayurveda as Alasaka. Or it may be expelled violently from the body, which is described as Vishoochika. Either way, the body is signalling that something has gone wrong in the process of digestion and assimilation. The manifestation can also differ depending on which dosha is involved. When Pitta is involved, you may see signs such as a burning sensation, excessive thirst, and disturbances in the mouth, reflecting more heat-related expressions. When Kapha is involved, it can manifest differently, with congestion-type conditions, urinary disorders, and other Kapha-dominant patterns. This is why Ayurveda does not look at digestion as simply a matter of what you eat. It considers the strength of Agni, the nature and quantity of food, the timing of meals, lifestyle, mental state, and the condition of the doshas together. Ama, in this sense, is not simply about having eaten something unhealthy. It is about what happens when the body is unable to properly process what it has received. What Are the General Properties of Ama? Ayurveda describes Ama as having certain characteristic properties. It is guru, meaning heavy and difficult to digest. It is drava, meaning it has a liquid nature. It is aneka-varṇa, meaning it can present in different colours. And it is picchila, meaning slimy or sticky in nature. The symptoms associated with ama are often the kind most of us have experienced at some point. There may be a sense of blockage or obstruction, general exhaustion, heaviness in the head, dizziness, stiffness in the back and hips, unusual thirst, and that general feeling that whatever you eat is simply not sitting right. Individually, none of these symptoms may seem particularly alarming. But when several of them appear together, they can indicate that something is not functioning properly within the digestive system. The answer is not always to simply eat less, eliminate one particular food, or ignore the discomfort and wait for it to disappear. Ayurveda asks us to look deeper at Agni. How strong is your digestion? Are you eating according to your hunger? Are you eating at regular times? Is the food appropriate for your digestive capacity? Is your lifestyle supporting digestion, or constantly working against it? Because digestion is not merely about what happens to food after you swallow it. It is about how well the body is able to transform what it receives into nourishment. If ideas like Ama and Agni interest you, our courses on Charaka Samhita and Ashtanga Hridayam go much deeper into understanding digestion, imbalance, and the way our body responds to what we eat, how we live, and how we care for ourselves.

Samanya and Vishesha: The Ayurvedic Principle of Balance

Think of this situation, you probably find it familiar. You come home tired, and instead of hitting the gym or going for a walk, all you want to do is sleep. So, you lie down but when you get up instead of feeling refreshed, you feel even more tired. There might also be days when you feel jittery and restless instead. So, you go for a walk or hit the gym hoping it will help. But rather than feeling energised, you end up feeling even more wired than when you started. You must have noticed that nobody has really taught us this. We just vaguely assume that rest will fix our tiredness, or movement will fix our restlessness, without actually stopping to think about whether they really do. Interestingly, Ayurveda has actually talked about this phenomenon. The Charaka Samhita has a verse that describes this very pattern. सामान्यमेकत्वकरं, विशेषस्तु पृथक्त्वकृत् । तुल्यार्थता हि सामान्यं, विशेषस्तु विपर्ययः ॥ It can be roughly translated to Samanya brings things together, Vishesha pulls them apart. Samanya is sameness of quality; Vishesha is its opposite. This verse introduces us to two words. One is samanya, which means sameness or similarity. The other is vishesha, which means difference or distinction. And the principle the text is pointing towards is that things that are similar to each other tend to increase each other, while things that are opposite to each other tend to reduce each other. It’s almost like fields, where one thing can either reinforce what is already there or counter it. Rest is slow. So, if you are already feeling heavy and slow, more rest isn’t necessarily going to rebalance you. It only reinforces that feeling of heaviness and sluggishness. On the other hand, restlessness is hot and fast. So, if you respond to that feeling with more movement, you might end up feeling even more hot and wired rather than actually calming the restlessness. You’re reinforcing the qualities that are already present. Now that we think about it, it sounds obvious. But we rarely think about our own habits in these terms. This principle can also be applied to the food we consume and our body’s internal balances, what Ayurveda calls the doshas. It’s quite simple. Whatever quality is already present in excess, you don’t add more of it. You reach for its opposite instead. On a cold day, for example, if you’re already feeling stiff, dry and cold you naturally want to add some warmth. Similarly, if you’re feeling sluggish or heavy after a meal, you probably don’t want to eat something even heavier, right? You want something lighter. In fact, the very first chapter of the Charaka Samhita, called Dirghanjivitiya, which is about the desire for long life, talks about exactly which tastes can calm which imbalances. It goes through all six rasas, or tastes, and explains their qualities and what can be used to pacify different states. Take Vata, for example. Vata is dry and is associated with movement. So, it is calmed by substances with opposite qualities. If you’re feeling dry and cold, if you’re in a Vata state, you would reach for sweet, sour and salty tastes because these carry qualities of moisture, warmth and weight. Or if you feel like your Pitta is rising, you’re overheated or you’re feeling short-tempered, bitter and sweet tastes can help cool things down. And this is important: none of the six tastes are universally good or universally bad. It’s not that sweet is unhealthy and bitter is healthy. Each taste has its place whether it is helpful or unhelpful depends entirely on the state it is meeting. There is no fixed list where cold foods are always bad or sweet foods are always bad. It depends entirely on the person, the place, the timing, and the state of the body, not just the substance itself. This is one of the core ideas of Ayurveda. It is individualistic. The same food or medicine can be helpful for one person but not for another. If you must have also noticed, even for the same person, something that suits them one day may not suit them on another day. It depends on what qualities they are already carrying in excess at that particular time. Ayurveda says that even a well-known poison, used with the right knowledge, at the right dose, for the right person, can become the best possible medicine. And a substance that’s technically medicine, used without that understanding, can do as much damage as poison. The substance alone is never the whole story. You have to look at what you’re giving, who you’re giving it to, why you’re giving it, how much you’re giving, and under what circumstances. And this brings us back to samanya and vishesha. Because the real question isn’t simply, “Is this food good?” Ayurveda’s answer is rarely just about the thing itself. It is about the relationship between the thing and the person receiving it. If this way of looking at Ayurveda interests you, you might enjoy our courses on the Charaka Samhita and Ashtanga Hridayam, where we go deeper into the texts and the ideas behind them. Sometimes, going back to the original texts can change the way you understand Ayurveda, and even the way you look at your own life.

Amla: Everything I Tell My Patients About How To Have It

Someone asked me the other day if I like matcha. No. I have something better. And we Indians have had it forever. It is amla. Our humble Indian gooseberry. Now everybody will tell you amla is good. Amla is good, amla is good. But nobody is telling you how much to have, when to have it, in what form, and what to do if you cannot get it fresh. So that is what I am going to tell you here. Exactly what I tell my patients. First, what amla actually is in Ayurveda In Charaka Samhita, amalaki is placed in the vayasthapana mahakashaya. That is the group of ten drugs classified as age sustaining. Age sustaining. Not anti-ageing. There is a difference, and Ayurveda made that difference two thousand years back. Now here is what most people get wrong. Amla tastes sour. So everybody assumes it is heating. It is not. Amalaki is sheeta virya. Cold in potency. And madhura vipaka. Sweet after digestion. This is what Bhavaprakasha Nighantu tells us. So, both of these are going against what your tongue is telling you. Your tongue says sour, your mind says heating. But that is not what is happening inside. And this is exactly why amla calms pitta, when almost every other sour thing will increase it. And that sweetness you feel in your mouth after eating amla, especially when you drink water on top of it? That is not vipaka. Vipaka is happening hours later, in your tissues. People mix up these two all the time. The best form is the fruit. Always. One amla a day itself is great. That is the whole thing. If fresh amla is naturally available to you, please have it like that. Do not overthink it. Do not go looking for a supplement. The fruit is the best form and nothing beats it. And amla comes in the cold season. That is not by accident. Nature is giving it to you exactly when you need it, so that is when you should be having it. So, when it is in season, eat it. Every day. Your body knows what to do with it. If you cannot get fresh amla, then powder Now most of you reading this are not in India. I know. Half of my patients are in places where amla is only available as a powder in a packet. That is okay. Powder works. But please listen to me about the quality. Get organic. Get good quality. And I mean really check. Because we have no idea where these people are drying it. We have no idea where they are powdering it. We have no idea what it went through before it came into that nice looking jar. So, if you are not sure about the source, better to avoid it. Really. Do not have it at all rather than having something you cannot trace. But if you are sure, if you know where it was dried and how it was powdered and how authentic it is, then go ahead. Find the best quality you can. I know I am dragging on too much about quality. I know. But this is more important than the dose, more important than the timing, more important than anything else in this whole article. A bad powder is not a weaker amla. It is a completely different thing. How much: one teaspoon of powder mixed into your food. That is the easiest way and the safest way, and this is what I tell most of my patients. Amla juice, please read this part carefully You can have amla as a juice. But as a shot. Not as a glass. Never drink a full glass of amla juice. Please. Do not take ten, fifteen amlas and make a big juice out of it and sit and drink it. Do not do it. Instead do this: Crush two or three amlas Add a little water Add pepper, turmeric, dry ginger A little Himalayan pink salt If you do not like the salt, add mishri or rock sugar instead And have it like a shot. Not more than 25 ml. That is it. Every day in the morning. That is enough. Timing and Anupana Morning is good. Have your shot in the morning. If you have a very strong acidic stomach, then have it after food. It works just as well and it is gentler on you. Anupana for amla is always water. Keep it simple. And there is one more way which I love, and most people have not even heard of it. Take amla powder, mix it with a little ghee, and have it with the first morsels of rice at lunch time. Beautiful way to take it. You can do the same at dinner also. Now, amla does not cause acidity I have to correct this one, because I am hearing it constantly. Amla does not cause acidity. It cannot. Once it goes into your stomach it cools down and it turns into sweet taste. It is not going to heat you and it is not going to burn you. It actually reduces acidity. Now if your stomach lining is already raw and inflamed, a concentrated shot on an empty stomach can still feel like too much for you. But that is the concentration doing it, not the amla. And that is exactly why I said have it after food. And see the irony here. People think curd is cooling. It is not. Classically dadhi is ushna virya with amla vipaka, and it is abhishyandi, it blocks your channels. It is doing almost the opposite of… Continue reading Amla: Everything I Tell My Patients About How To Have It

Ojas: The Ayurvedic Concept Modern Medicine Doesn’t Have a Word For

Before we talk about Ojas, let me ask you a question. What keeps you from falling sick? Your answer would probably have been immunity, right?! Ayurveda has a broader concept for this term called immunity, it’s called Ojas. Most people, when talking about Ayurveda, must have heard or come across its fundamental concepts like Doshas and Agni. But very few have heard of Ojas, even though classical texts like the Charaka Samhita treat it as one of the most important substances in the body. So what exactly is it? Ayurveda describes Ojas as the final, most refined product of digestion. Food is broken down and transformed through seven progressive tissue layers, called Dhatus, each one nourishing the next. At the very end of this chain sits Ojas, described as the essence that remains once digestion and tissue formation have been completed properly. In simple terms, Ojas is what your body produces when everything upstream, digestion, absorption, sleep, stress and lifestyle, is working the way it is supposed to. This is very different from how modern medicine defines immunity. Modern immunology has largely been about defence. It studies how white blood cells recognise a threat, how antibodies respond to an infection, how inflammation rises and eventually settles down. So much of the field is built around one fundamental question: what does the body do to fight disease once the disease has already appeared? Ayurveda asked a slightly different question. Instead of only asking how the body fights disease once it appears, it asked what keeps a person resilient enough that disease struggles to take hold in the first place. This is where Ojas becomes more than just another word for immunity. It points to the body’s underlying capacity to remain nourished and resilient. Ayurveda describes Ojas as responsible not only for physical resistance to illness, but also for mental steadiness, emotional stability and general vitality. A person with strong Ojas is described as calm and capable of recovering quickly from physical or emotional strain. A person with depleted Ojas is described as fatigued, anxious and repeatedly falling ill. Sounds familiar? This is remarkably close to a field in modern medicine called psychoneuroimmunology, the study of how the mind and the immune system influence each other. Research in this space has repeatedly shown that chronic stress suppresses immune function, lowers the activity of certain immune cells, and disrupts hormonal balance over time. Ayurveda arrived at a this conclusion, though earlier and through a completely different method. According to Ayurvedic texts, Ojas exists in two forms. Para Ojas, a small, fixed reserve said to be located in the heart, considered essential to life itself. And Apara Ojas, a larger, circulating form that fluctuates based on how a person lives. Apara Ojas is what rises with good digestion, adequate sleep, emotional balance and a stable routine. It is also what depletes with poor diet, chronic stress, overexertion and disrupted sleep. This is an important detail, because it means Ayurveda never treated immunity as fixed. It treated it as something built daily, and something that can just as easily be worn down daily. That idea alone reframes a lot of modern health conversations. We tend to think of immunity reactively. Ayurveda asked people to think of it proactively, as something to be cultivated through Ahara, or diet, Nidra, or sleep, and Brahmacharya, a disciplined, balanced lifestyle. Rasayana, the branch of Ayurveda focused on rejuvenation, exists almost entirely around this idea. Its routines and therapies are not designed to treat a specific illness but to strengthen Ojas itself, on the belief that a body with strong Ojas is naturally less susceptible to disease in the first place. This is a meaningfully different starting point from most of modern healthcare, where treatment typically begins after a diagnosis. None of this means Ayurveda and modern immunology are describing identical things. Ojas is a broader, more integrated concept, tying together digestion, sleep, emotional health and physical resilience in a way modern immunology usually studies as separate systems. But the overlap is close enough that researchers today are actively exploring where classical descriptions of Ojas align with measurable biomarkers of immune and stress response. Which brings us back to the original question. If Ayurveda already had a framework for resilience that considered the body and mind as one system, why did it stay this unfamiliar to most people? Likely for the same reason so much of Ayurveda’s deeper philosophy gets overlooked. Concepts like Ojas require explanation, context and patience to be understood. But this is also exactly why concepts like Ojas are worth understanding properly, and not just referencing in passing. Because long before immunity became a trending word, Ayurveda had already built an entire framework around what it actually takes for a body to stay resilient, not just after illness, but before it ever begins. If topics like this interest you, our courses on Charaka Samhita and Ashtanga Hridayam explore concepts like Ojas in far greater depth, straight from the original texts.

5 Ways Ayurveda Understands Food and Digestion

Most of us consider food in terms of calories, protein, carbs, or whatever the latest diet trend tells us we should be eating. Ayurveda looks at food a little differently. Food is not just fuel in Ayurveda. It can affect digestion, energy levels, mood and general well-being. Ayurveda asks not just, “How much should I eat?” but “What am I eating? When am I eating it? And is it right for me?” And to understand this way of looking at food, we first need to understand how it describes food and its effects on the body. Here are five ways Ayurveda understands food, digestion and eating. Food Is Understood Through Six Tastes, Not Just Flavour In Ayurveda, taste is not only a matter of enjoyment, but is seen as a direct indication of the effect a food has on the body. The shad rasa, or six tastes, are mentioned in the classical texts: sweet, sour, salty, pungent, bitter and astringent. Every taste has its effects and qualities. Sweet foods for example have traditionally been seen as building and nourishing. Bitter foods are considered to be lightening and detoxifying. Pungent foods are supposed to stimulate digestion. It is not that any one taste is inherently ‘good’ or ‘bad’, a well-balanced meal or diet should ideally include a variety of tastes, since each one plays a different role in the body’s response to food. Digestion Is Treated as the Centre of Health One of the most fundamental principles of nutrition in Ayurveda is the concept of Agni, or digestive fire. Agni refers to the body’s capacity to process and transform what we take in, not just food, but also experiences and emotions. Even the most nutritious diet cannot be considered useful if the body cannot process it well. That is why it is equally important to pay attention not just to what we eat, but also to our ability to digest it. How do we measure that? Your body is always giving you signals. If you feel sluggish or bloated after having a heavy meal then it might be a sign of slow digestion. If your meals leave you with acidity, and you feel hungry very often, these may be signs that your digestion is not functioning optimally. That is why, Ayurveda emphasizes heavily on eating at regular times, being mindful when eating and avoiding overeating. Food Is Classified by Its Effect on the Body, Not Just Its Content In Ayurveda, food is not understood only by what it contains like the carbohydrates, proteins, fats, vitamins or minerals. It is also understood through its qualities and the way it affects the body after we eat it. Foods are described as heavy or light, hot or cold, dry or oily, among other qualities. These qualities help us understand how a particular food may influence digestion and the body. For example, some foods may be nutritious but still feel heavy or difficult to digest. This is why Ayurveda pays attention not just to the food itself, but also to how it is prepared, what it is combined with, and how it is eaten. Cooking, using spices and choosing the right combinations are not simply about making food more flavourful but are also considered ways of making food easier for the body to digest and use. So, in Ayurveda, eating healthy is not only about choosing the food with the best nutritional profile. It is also about understanding how that food interacts with your body. Seasons and Individual Constitution Shape What “Balanced” Means Ayurveda does not believe that there is one perfect diet that works for everyone. It looks at each person differently through the concept of the three doshas: Vata, Pitta and Kapha. These are understood as different combinations of qualities that influence how our body and mind function. This is why the same food may not affect everyone in exactly the same way. What feels light and comfortable for one person may feel heavy or unsuitable for another. Ayurveda also considers the season and environment when deciding what is appropriate to eat. Our needs can change with shifts in weather, temperature and routine. For example, the foods and habits that may feel appropriate during a hot summer can be very different from what suits the body during a cold or dry season. So, Ayurvedic nutrition is not about following a fixed list of “good” and “bad” foods. It is about understanding what your body needs at a particular time and in a particular situation. Food and Lifestyle Are Never Completely Separate Ayurveda does not look at food as something separate from the rest of our daily life. Sleep, stress, exercise, daily routine and even the time at which we eat can influence how our body handles food. Think about eating the same meal on two different days. One day, you may sit down calmly and eat without distractions. On another day, you may eat the same meal while rushing, working or feeling stressed. The food may be the same, but the way you experience the meal can be very different. This is why Ayurveda places importance not only on what we eat, but also on how, when and in what state we eat it. The idea is simple. Food is one part of our health, but our daily habits, routines and environment play a role too. Whether you’re simply curious about Ayurveda or want to study it seriously, understanding the classical texts is the best place to begin.

Agni: Why the Same Food Affects Everyone Differently

Ayurveda says that your body’s ability to digest and transform food into nutrients differs from person to person. Modern nutrition has also come to a similar understanding: everybody’s body is different. But let us look at this a little deeper. Imagine two people having the same meal, in the same quantity, at the same time. But one might feel energetic and satisfied after eating, while the other might feel bloated, heavy, or dizzy. So, how is that possible? This is because of what Ayurveda describes as Agni, or digestive fire. The strength and quality of your Agni determine how well your body digests food, absorbs nutrients, eliminates waste, and produces energy. In other words, it is not just what you eat that matters; how your body processes the food you eat matters just as much. And Agni is more than digestion. In Ayurveda, Agni is more than just digestive enzymes or stomach acid. It represents the entire process of transformation happening inside your body, from breaking down food to supplying energy, nourishing the tissues, and supporting immunity. Ayurveda describes 13 different types of Agni, with the most important one being Jatharagni, the main digestive fire located in our digestive tract. When we talk about the overall state of digestion, Ayurveda mainly focuses on four different types of Agni. Each one reflects a different pattern of digestion and relationship with food. Let’s look at them in detail. Sama Agni: Balanced Digestion Sama Agni is considered the ideal state of digestion, where your Agni is balanced, your food gets processed efficiently, and you get hungry at regular intervals of time. Your appetite is steady. Your energy remains stable throughout the day, and you feel satisfied after eating your meals. So, someone with Sama Agni has a healthy ability to digest and process food efficiently. That does not mean they can eat unhealthy food all the time. It simply means that their digestion is functioning the way it should. The goal is not to have a digestion that allows you to eat anything without consequences. The goal is to have an Agni that is balanced enough to digest, transform, nourish, and eliminate efficiently. Vishama Agni: Irregular Digestion The second type is Vishama Agni. Vishama means irregular, and it describes digestion that is irregular or unpredictable. Some days you may have a good appetite, while on other days, you may not feel like eating at all. Some days you may feel bloated after eating or sluggish after your meals. You may also experience irregular bowel movements. This pattern is mostly associated with aggravated Vata, which is linked with movement and irregularity within the body. When Vata becomes irregular, digestion can also become irregular. People with Vishama Agni may find that their hunger, digestion, bowel movements, and even their response to food can change from day to day. So, how do you overcome this? It can be as simple as maintaining consistent meal times, eating warm, home-cooked meals, and following a steady daily routine, or Dinacharya. Because Vata is a quality that drives irregularity, it can be calmed by consistency. Sometimes, the answer is not another supplement or another complicated diet. It is simply giving your body a predictable rhythm. Tikshna Agni: Sharp or Intense Digestion The third is Tikshna Agni, which means sharp or intense digestion. This is when your digestion becomes strong and fast, and sometimes, too strong. People with Tikshna Agni may experience intense or frequent hunger. They might get hungry very quickly, digest food very quickly, and may be able to tolerate spicy or heavy meals. At first, this might sound like something good. But Tikshna Agni is often linked with aggravated Pitta, which is associated with heat and intensity. If it is not managed well, you may experience acidity, heartburn, excessive heat, or inflammatory-type conditions. The goal here is not to suppress digestion, but to balance its intensity. It is suggested to take moderately cooling foods in nature and avoid excessive spice or very hot, acidic foods. Instead of skipping meals, maintain a regular Dinacharya, eat at consistent times, and stay adequately hydrated. When Agni is too sharp, giving it more stimulation is not necessarily the answer. Sometimes, it needs moderation. Mandagni: Slow or Weak Digestion The fourth type is Mandagni. Manda means slow or weak. Mandagni is characterised by a low appetite and slow digestion. After eating your meals, you may feel sluggish, heavy, or lethargic. You might also experience mental fog after eating. Over time, this heaviness may also affect how you feel mentally as well. Mandagni is associated with aggravated Kapha. This is also the condition most directly linked with Ama accumulation in Ayurveda. Ama is often described as a form of accumulation that can occur when food and metabolic processes are not properly processed. Because the digestive fire is slow, food is not processed efficiently. This can lead to partially digested material accumulating in the system, which Ayurveda describes in terms of Ama. This is why Ayurveda does not look at digestion simply as whether you are eating the “right” food. The same food can affect two people differently because their Agni may be different. One person may eat a meal and feel energetic, satisfied, and comfortable. Another person may eat the exact same meal and feel heavy, bloated, sluggish, or uncomfortable. The food is the same. But the person processing the food is not. And this is one of the reasons Ayurveda places so much importance on Agni. It is not simply about what enters the body. It is also about the body’s ability to transform what enters it. Understanding your Agni gives you a different way… Continue reading Agni: Why the Same Food Affects Everyone Differently

Why Two Healthy Foods Don’t Always Belong Together?

Sometimes I believe we look at food in a very simple way, in the sense that we don’t question it. We look at two foods that are healthy, like for example, a fruit is healthy, milk is healthy, and yogurt is healthy. Then we think, okay, if we mix these two healthy foods, the result will also be healthy. But that is not always true. More than 2,000 years ago, the Charaka Samhita introduced a concept called Viruddha Ahara, which means incompatible food combinations. The idea behind this is that a food is not only judged by what it is, but also by how it is eaten, how it is prepared, what it is eaten with, and who is eating it. Taking all these factors into account is important because two foods can be good on their own, but when combined, may not result in a good combination when eaten together. This is a very different way of thinking about food and nutrition. Normally, the questions that pop into our mind when we think about food are: Is it high in protein? Does it contain any vitamins? Is it low in sugar? Or is it natural or processed? But we should ask different questions. What is this food being combined with? How is it being prepared? Is the right amount being consumed? Is it the right season to eat it? Can my digestion handle it? Now, instead of looking at foods one by one, Ayurveda looks at the relationship between foods. According to the Charaka Samhita, there’s not just one kind of food incompatibility. There are 18 different ways in which food can become unsuitable when combined. Keep in mind that food is affected by where, when, how, how much, and with what it is eaten. Let us look into some of the most important types of Viruddha Ahara. First is Desha Viruddha, which means some foods are better suited to certain climates than others. A food that might work well in a cold region might not be the best choice to be eaten in a hot or humid place. Kala Viruddha refers to, as the name signifies, the season and time of the day. Eating heavy and oily foods during summer, or eating meals that are difficult to digest at night, might not suit the body and is not suggested. Agni Viruddha means digestive strength. Not everyone can digest food in the same way. A meal that might feel light for one person may feel heavy and uncomfortable for someone with weaker digestion. Matra Viruddha means quantity. Even healthy food becomes unhealthy when taken in excess amount. It is important to keep in mind that the right amount of food is as important as the right food. Then there is Samskara Viruddha. The way food is cooked, stored, and processed also changes how it affects the body. The same ingredients may have different effects depending on how they are prepared. Virya Viruddha refers to the inherent qualities of food. Some foods have warming qualities, while others have cooling qualities. Combining foods with opposite properties might not always be a good choice. Samyoga Viruddha refers to foods that do not work well together, even when each of them is healthy on its own. One of the best-known examples of Samyoga Viruddha is milk with sour fruits. According to Ayurveda, milk has a cooling nature, while sour fruits are heating and acidic. The classical texts explain that this combination can disturb digestion, increase heaviness, and create discomfort. Many people may have experienced this without realizing, like after consuming certain fruit-and-milk combinations, such as a smoothie or milkshake, they may feel bloated, heavy, or simply feel that the meal “didn’t sit well.” Now, Viruddha Ahara is not just a small idea presented in Ayurveda. It is an important concept because it is considered one of the major causes of disease. In the Charaka Samhita, incompatible food combinations are described as a major reason for several health problems, especially those related to the skin. They are also linked with inflammation, poor digestion, and, in some cases, even disturbances of the mind. Vagbhata has also described incompatible food combinations as being poison-like. This doesn’t mean they act like a poison after every single meal. It means that when these combinations are consumed repeatedly over months, they might gradually affect your health. The effects may show up as bloating, discomfort, inflammation, and other digestive issues. So, the next time you are trying to consume something healthy, ask yourself if that combination of foods or ingredients is actually healthy for your body.
