Charaka Samhita Part 7: Sutrasthana Chapter 7 (Naveganadharaniya Adhyaya) — The Natural Urges You Should Never Suppress (And How to Exercise Safely)

📖 23 min read · Part 7 of the Charaka Samhita Series

Why This Chapter Is the Most Practical One Yet

The first six chapters of the Charaka Samhita build the foundation: the goal of long life, cleansing herbs, herbal pastes, the great herb groups, how much to eat, and the seasonal routine. Chapter 7 turns from the kitchen and the calendar to the body itself — to its involuntary rhythms, its appetites, and its waste. It is, in many ways, the most directly usable chapter so far, because almost everything in it is a decision you make several times a day without thinking.

Do you go to the toilet when your body asks, or do you finish the email first? Do you stifle a sneeze in a meeting? Do you push through a workout when your body is begging you to stop? Do you let anger run your mouth? The Naveganadharaniya Adhyaya answers exactly these questions, and it answers them with a clarity that is almost startling for a text more than two thousand years old. Its core teaching is simple: honour the body's natural calls, restrain the mind's harmful ones. Get that one distinction right, the chapter argues, and a surprising number of diseases never get started.

What "Naveganadharaniya" Means

As always in the classics, the chapter's name is its thesis. Na (न) means "not." Vega (वेग) means an urge, an impulse, a natural pressure that builds and seeks release. Dharaniya (धारणीय) means "to be held back" or "to be suppressed." Put together, Na-vegan-dharaniya means "the urges that are not to be suppressed."

That single word already tells you the chapter's most famous idea: there is a class of bodily urges that the wise person never forces back. The text states the principle plainly — the wise should not suppress the natural urges (Charaka Samhita, Sutrasthana 7.3–4). But the chapter is broader than its title. Having drawn the line at physical urges, it goes on to draw the opposite line for mental ones, then moves through exercise, habit-change, body type, the body's waste channels, yearly cleansing, good conduct and even a caution about curd. It reads like a senior physician's notebook of "things every patient should know."

The Natural Urges You Should Never Suppress (Adharaniya Vega)

The urges the chapter protects are the body's involuntary signals — the calls of nature in the most literal sense. In Ayurvedic language these are the adharaniya vega (अधारणीय वेग): the "non-suppressible urges." The classical tradition enumerates thirteen of them, and Vagbhata lists the very same thirteen in his parallel chapter, which we cover in detail in our guide to Vegadharana in the Ashtanga Hridaya. They include the urges to pass wind, to pass stool and urine, to sneeze, to feel thirst and hunger, to sleep, to cough, to breathe hard after exertion, to yawn, to shed tears, to vomit when the body wants to, and the reproductive urge.

What unites them is that they are downward and outward movements governed largely by Vata (वात), the principle of movement in the body. When the body decides it is time to release something — air, water, waste, heat, emotion — it generates a Vega, a pressure. The healthy response is to give that pressure a clear, unhurried path out. The unhealthy response is to clamp down on it because it is inconvenient, embarrassing, or badly timed. Do that often enough, the chapter warns, and the trapped Vata turns back on the body and begins to cause disease.

A useful way to picture it: each of these urges is the body opening a valve. Sneezing clears the nose and sinuses; passing wind and stool relieves pressure in the gut; tears protect the eyes; the urge to sleep is the nervous system asking to power down and repair. Force the valve shut and the pressure does not simply vanish — it backs up. In Ayurvedic terms, that backed-up movement is disturbed Vata, and the chapter's whole point is that letting it flow on time is one of the cheapest forms of prevention there is. The fix is almost insultingly simple, which is exactly why it is so easy to neglect.

This is one of those places where a 2,000-year-old text is uncomfortably accurate about modern life. Almost everything about an office day teaches us to override these signals: hold the bathroom break until the call ends, swallow the yawn, suppress the cough, skip lunch through hunger, push sleep back another hour. None of these feels harmful in the moment. The chapter's insight is that the harm is cumulative and quiet — a slow disturbance of the body's natural direction of flow.

What Happens When You Hold Them Back — and How the Text Treats It

Chapter 7 does not merely say "do not suppress." It catalogues what goes wrong when you do, and — crucially — it prescribes how to set it right. The text lays out the symptoms and treatment of suppressing the natural urges (Charaka Samhita, Sutrasthana 7.3–4), and then devotes a long stretch of verses to the remedies (Sutrasthana 7.5–24).

The pattern of relief is consistent, and it is essentially a programme to settle disturbed Vata. The chapter's prescribed measures, taken together, include:

• a fatty (unctuous), warm and light diet — food that is easy to digest and carries the qualities opposite to the dry, cold, rough nature of aggravated Vata;
• cold and saturating drinks where the disturbance calls for them, to nourish and settle;
• sleep, and pleasant, reassuring talk — rest and a calm mind, treated as medicine in their own right;
• gentle pressing and massage of the body — what we would recognise today as warm oil massage (abhyanga) and soothing touch;
• rest and measures that specifically alleviate Vata (Sutrasthana 7.5–24).

Read that list again and notice how humane it is. The treatment for ignoring your body is, in effect, to stop ignoring your body: feed it warm and easily, let it rest, calm the mind, and apply gentle, grounding touch. There is no harsh purge here, no punishment — just a return to the warm, moist, settled qualities that Vata loses when it is forced back. This is the law of opposites we met in Part 1's Tridosha framework applied to a very ordinary problem.

One detail is worth underlining: the chapter treats the management as individual, not generic. The right relief depends on which urge was suppressed and how the body responded — a person who routinely holds urine needs different care from one who chronically overrides sleep or hunger. But the direction of treatment is always the same: restore warmth, moisture, ease and rest to a system that has been made dry, tight and agitated. If you take only one habit from this chapter, let it be this — when a natural call comes, stop what you are doing and answer it.

The Urges You Should Always Restrain (Dharaniya Vega)

Here the chapter makes its most elegant move. Having insisted that physical urges must never be suppressed, it immediately defines a second, opposite category: the urges that should always be held back. These are the dharaniya vega (धारणीय वेग) — the "suppressible urges" — and they are not physical at all. They are the impulses of mind, speech and action that, if acted on, harm yourself or others.

The text describes these as the urges of "evil venture related to thought, speech or action," and it names them with unsparing precision (Charaka Samhita, Sutrasthana 7.26–29):

• Of the mind: greed, grief, fear, anger, vanity, shamelessness, envy, excessive attachment, and the desire to take what belongs to another;
• Of speech: talk that is harsh, that betrays a confidence, that is false, and that is spoken at the wrong time;
• Of the body: actions that cause pain to others — the text names adultery, theft and violence.

The symmetry is the whole point. A natural urge is the body asking for what it needs; suppress it and you harm yourself. A harmful urge is the mind reaching for what it wants at another's cost; act on it and you harm everyone, yourself included. Maturity, in the Charaka Samhita's view, is knowing which kind of urge you are feeling and responding to each in the opposite way. This is why Ayurveda has always treated conduct (Sadvritta) as a branch of medicine rather than a branch of ethics: an agitated, greedy, fearful mind is, to the classical physician, a sick mind, and it makes the body sick in turn.

Exercise the Right Amount (Vyayama)

From urges, the chapter turns to Vyayama (व्यायाम) — physical exercise (Charaka Samhita, Sutrasthana 7.31–33). Ayurveda is enthusiastic about exercise: in right measure it brings lightness, strength, firmness of the body, tolerance of hardship, and a better-burning digestive fire. But the chapter is just as firm about the limit, and it delivers the warning with one of the most memorable images in the entire Samhita.

The image is perfect. A lion is powerful enough to bring down an elephant, yet a lion that tries to drag one will tear itself apart in the attempt. Strength is not the issue; overreach is. The same applies to a fit body pushed past its capacity. And note how broad the list is — it is not only the gym. Excessive laughter, excessive talking, excessive walking, excessive sex, and staying up through the night are all placed in the same category of self-depleting overexertion, "even if he is accustomed to them." Habit, the text warns, is no protection; the body you trained yesterday can still be torn by today's excess.

Why is Ayurveda so cautious about a thing it also praises? Because exercise, like fire, is useful only within limits. In right measure it kindles the digestive fire, clears the channels, firms the body and steadies the mind. Pushed past capacity, the very same effort drains the tissues it was meant to build, and in a hot, dry or already-depleted state it can do real harm. The classical teachers gave a simple, embodied gauge for "enough": stop when sweat first beads on the forehead, nose and underarms and the breath begins to move to the mouth. That moment — effort clearly begun but not yet exhausting — is roughly half one's capacity, and it is where the benefit lives.

The practical teaching is one of measured effort. Exercise to about half your capacity — to the point where effort first appears in the breath and forehead, not to collapse. For Ayurveda, the goal of exercise is a body that feels lighter and stronger afterward, not one that feels wrecked. This is also why exercise is matched to constitution and season: what builds a strong Kapha person in winter can break a delicate Vata person in the dry months. We unpack the seasonal half of that equation in our daily routine guide.

Changing Bad Habits the Gradual Way

Knowing what to do and actually changing how you live are two different things, and Chapter 7 is unusually wise about the gap between them. It gives a method for replacing bad habits with good ones — and the method is gradual, not heroic (Charaka Samhita, Sutrasthana 7.36–37).

The instruction is to change by quarters. On the first day, give up one-quarter of the unwanted habit and adopt one-quarter of the new one. On the next day, shift a further portion. Continue in steps, spaced at intervals of two or three days, until the change is complete. Done this way, the text promises, "faults are removed permanently and merits become unshakable" (Sutrasthana 7.36–37).

Modern behavioural science arrived at the same conclusion only recently: gradual, staged change holds, while sudden total reversals tend to snap back. The Charaka Samhita knew it long ago. If you have read our companion article on building an Ayurvedic daily routine, this is the engine that makes a new routine stick: do not overhaul your life on a Monday — change it a quarter at a time.

Why the Rules Bend for You: Body Constitution (Prakriti)

If you have ever wondered why a food or routine that suits your friend leaves you unwell, Chapter 7 gives the classical answer. It introduces Prakriti (प्रकृति) — your individual body constitution — and it traces it all the way back to your beginning.

From the very time of conception, the text says, some people are born with an equilibrium of Vata, Pitta and Kapha, while others are vatala, pittala or slesmala — that is, constitutionally dominant in Vata, Pitta or Kapha respectively (Charaka Samhita, Sutrasthana 7.39–40). Those born in balance tend to be the most disease-free; those with a strong inborn dominance of one dosha are more prone to its disorders throughout life. The text gives a beautifully compact definition: body constitution is the "ever attachment" of a particular dosha (Sutrasthana 7.40) — the dosha that is, in a sense, permanently attached to you from birth.

This is one of the most consequential ideas in all of Ayurveda, because it explains why there can be no single "best diet" or "best routine" for everyone. Your constitution is the baseline the rest of the chapter's advice is tuned against. We explore the seven classical constitution types and how to recognise yours in our detailed guide to Prakriti in the Ashtanga Hridaya.

There is an important corollary in the same chapter. For the rare person whose tissues (dhatus) are already in perfect equilibrium, the text says the balanced use of all six tastes (rasas) equally is wholesome (Charaka Samhita, Sutrasthana 7.41). In other words, only a body already in balance can afford to eat freely across the whole range of tastes; the rest of us must lean, gently, toward the tastes that counter our dominant dosha. Constitution is not a label to box yourself into — it is a compass for which corrections matter most for you.

The Body's Drainage Channels and Wastes (Mala)

Having covered intake and effort, the chapter turns to output — the body's malas (मल), its wastes, and the passages through which they leave. This is the original "body cleansing," and it is refreshingly concrete. The text counts the body's main excretory passages (Charaka Samhita, Sutrasthana 7.42):

• the two lower passages — the anus and the urethra;
• the seven openings in the head — two eyes, two ears, two nostrils and the mouth;
• and the sweat glands and other cutaneous (skin) glands, through which the body releases waste continuously.

These passages, the text explains, become blocked when the excreta they carry become "excessively vitiated" — that is, when waste accumulates faster than it can leave (Sutrasthana 7.42). Healthy elimination keeps the channels open; sluggish or overloaded elimination clogs them, and clogged channels are where many disorders begin.

How do you read your own elimination? The chapter gives two plain checklists — the signs of too much waste, and the signs of too little (Charaka Samhita, Sutrasthana 7.43):

Notice that both extremes are problems. Ayurveda does not chase maximum elimination any more than it tolerates blockage; it wants balanced output. Heaviness and constipation say waste is building up; excessive sweating, urination or loose stool say the body is losing too much. The healthy middle — easy, regular, complete elimination through open channels — is the everyday version of the deeper cleansing the chapter describes next.

Seasonal Cleansing and Rejuvenation (Panchakarma and Rasayana)

Daily elimination keeps the channels open, but Chapter 7 also recommends a deeper, periodic reset. It describes a yearly programme of Panchakarma (पञ्चकर्म) — the classical bio-cleansing therapies — followed, in a specific order, by rejuvenation (Charaka Samhita, Sutrasthana 7.46–50).

The sequence matters. First comes the cleansing (Panchakarma) to clear accumulated waste from the channels. Only then, on a clean foundation, come the rasayanas (रसायन) — the rejuvenating tonics — and, last and according to suitability, the aphrodisiac (vajikarana) measures. Order is everything: you cleanse, then you nourish, then you strengthen. Nourishing a clogged body simply feeds the blockage; this is why the text fixes the sequence so carefully.

The promised result is one of the most quietly inspiring lines in the chapter: when the tissues have been stabilised in their normal condition this way, "diseases do not arise, the tissues are promoted, and aging is slowed down" — and the text recommends doing this yearly, as a standing programme to prevent disease (Charaka Samhita, Sutrasthana 7.46–50). This is preventive medicine in its purest form: not a cure scrambled together after illness strikes, but an annual tune-up that keeps illness from arising at all. For a gentle, at-home version of the cleansing idea, see our 7-day Ayurvedic cleanse plan — though full Panchakarma should always be done under a qualified physician.

Good Conduct and the Company You Keep (Sadvritta)

The chapter closes its broad sweep with mental and social health, and it does so with a claim that sounds strikingly modern: exogenous diseases of body and mind are caused by errors of intellect — by doing what we know we should not (Charaka Samhita, Sutrasthana 7.51–55). The remedy it prescribes is a code of right living: forsake those errors of judgement, calm the senses, cultivate memory and a sound knowledge of place, time and one's own self, follow the code of good conduct, and heed the advice of wise authorities.

Then it gets specific about other people, because the company you keep shapes the mind that keeps you well. The text draws up two lists. The people to avoid include those given to vicious action, speech and thought; informers and the quarrelsome; those who ridicule others' weak points; the greedy and the envious; the crooked and those who blackmail; the unstable, the cruel, and those who have abandoned the virtuous path (Charaka Samhita, Sutrasthana 7.56–57). The people to keep company with are their opposite: those endowed with wisdom, learning and good conduct; the calm and balanced of mind; those who keep the company of elders and know the nature of things; the peaceful, and those whose very speech and presence are wholesome (Sutrasthana 7.58–59).

It is easy to dismiss this as moralising, but the chapter frames it as medicine, and the framing is deliberate. An anxious, resentful, fearful mind keeps the body in a low-grade state of disturbance; a steady, content mind lets the body settle and heal. Twenty-five centuries before the phrase "your environment shapes your health," the Charaka Samhita prescribed good company as a clinical intervention.

There is a thread running through this whole closing section: Sadvritta (सद्वृत्त), the "code of good conduct," is not an add-on to Ayurvedic health but part of its core machinery. Calm the senses, keep honest company, and act in line with what you know to be right, and the mind stops manufacturing the disturbances that the body then has to absorb. It is the same prevention-first logic the series met in Chapter 1, now turned inward toward character and relationships.

A Practical Diet Caution: Curd (Dadhi)

The chapter ends on a wonderfully specific, kitchen-level note — a caution about curd (Dadhi, दधि), the everyday Indian yoghurt. Curd is nourishing, but the text considers it heavy and heating if used carelessly, and it lays down clear rules (Charaka Samhita, Sutrasthana 7.61):

And the consequence of ignoring the rule is spelled out without euphemism: one who is fond of curd and uses it recklessly suffers from fever, internal haemorrhage, erysipelas (a skin inflammation), anaemia, giddiness and severe jaundice (Charaka Samhita, Sutrasthana 7.62). Whether or not every modern reader accepts the full list, the underlying advice is sound and survives in Indian kitchens to this day: do not eat curd at night, do not eat it piping hot, and pair it with something — ghee, a little sugar, green-gram soup, honey or amalaka — that offsets its heavy, sour nature. It is a small example of the chapter's whole spirit: respect the body's responses, and adjust the everyday details so the body never has to fight your habits.

Living Chapter 7 Today

Strip Chapter 7 down to a daily discipline and it becomes one of the most usable pages in the Charaka Samhita:

• Answer the body's natural calls promptly. Toilet, water, food, sleep, a sneeze, a yawn — give each a clear path when it asks. The disease starts in the delay (Su 7.3–4).
• Restrain the mind's harmful urges. Greed, anger, fear, envy, harsh or false speech, the impulse to harm — these are the urges to hold back (Su 7.26–29).
• Exercise to about half your capacity. Aim for lighter and stronger, never wrecked; habit is no licence for excess (Su 7.35).
• Change habits a quarter at a time. Gradual, staged change holds where sudden reversals snap back (Su 7.36–37).
• Tune your routine to your constitution. There is no one-size-fits-all; lean toward what counters your dominant dosha (Su 7.39–41).
• Keep your channels open. Aim for easy, regular, balanced elimination — neither blocked nor excessive (Su 7.42–43).
• Cleanse before you nourish. Whether yearly or seasonally, clear first, then build (Su 7.46–50).
• Choose your company. Steady, wholesome people are, in the chapter's own logic, part of your medicine (Su 7.56–59).

None of this requires a clinic or a single exotic herb. It requires attention — the willingness to notice what the body is asking for and to answer honestly. That, in the end, is what the Naveganadharaniya Adhyaya teaches: the body is constantly speaking in the language of urges, and health is mostly a matter of listening.
