Sutrasthana 3.6 — When the Heat Is Calmed

When clouds, rain, and cold winds have stilled the heat upon the face of the earth, what builds strength here is the unctuous (snigdha) quality, together with the sour, salty, and sweet tastes.

Reading the Sanskrit Word by Word

The verse opens with a small, exact weather-picture before it says a word about food: megha-vṛṣṭy-anilaiḥ śītaiḥ śānta-tāpe mahī-tale — "when, by clouds, rain, and cold winds, the heat upon the surface of the earth has been quieted." Each agent of cooling is named in its turn. The clouds, megha, veil the sun that had been burning the sky. The rain, vṛṣṭi, soaks ground that the drying course had left parched. The cold winds, anilaiḥ śītaiḥ, are the precise reversal of the hot, scouring gales of the previous arc; the same word anila for wind, now qualified by śīta, cold. The locative compound śānta-tāpe — "the heat being pacified" — sets the whole second line in a particular moment, and that moment is the exact mirror of the scene in verse 3, where the sun and wind together were drinking the moisture out of the land. Here the verb of pacification has done its work, and mahī-tale, "on the surface of the earth," keeps the eye on the ground itself.

Only after the climate is established does the second line name what nourishes: snigdhāś cehāmla-lavaṇa-madhurā balino rasāḥ. The first item, snigdha, is not a taste at all but a quality — "unctuous, oily, smooth, moist" — the very lubrication that the dry (rūkṣa) heat of the depleting course had stripped from the body. Then come the three tastes, the three rasa: amla, sour; lavaṇa, salty; madhura, sweet. These are bound together by balinaḥ, "strengthening, full of strength," the word that decides the verse. The whole line reads as a single predication: in this cooled condition, the unctuous quality together with the sour, salty, and sweet tastes are what carry strength. The little particle iha — "here," embedded in the compound as ceha, "and here" — is easy to pass over, but it ties the whole counsel to the situation just named. It is here, in this cooled condition, on this rain-soaked earth, that these tastes strengthen; the same tastes elsewhere in the year were said to overload. The food is the same; the "here" is what has changed.

What the Verse Asserts Physiologically

The descriptive claim underneath the imagery is a claim about digestive fire. In the framework Vāgbhaṭa is building, the fierce drying heat of the northern course keeps the digestive fire — agni — scattered and weak, unable to manage heaviness, so that strength in that arc is preserved by eating light. When the rains and cold winds quiet that heat, the body's fire is described as gathering and strengthening in the cool, and the capacity to receive and assimilate rich food returns. The strengthening qualities named here are therefore precisely the ones that the same text treats as overburdening in summer. What was a load on a depleted system becomes fuel for a recovering one; nothing about the food has changed, only the body's capacity to use it.

The three tastes are the heavy, moistening, building flavors of Āyurvedic dietetics. In the standard reading, madhura (sweet) builds tissue and increases the body's substance, amla (sour) kindles appetite and moistens, and lavaṇa (salty) softens, retains fluid, and warms — and all three tend to nourish the dhātu, the bodily tissues, and to rebuild reserve. Set against them, the unctuous quality replaces the oiliness that the dry season consumed. So the verse describes a coordinated restoring of substance: fire strong enough to digest, tastes that build, and the moisture that the heat had taken. This pacifies the dryness and lightness that the depleting arc had raised, especially in vāta, and refills what was drawn down.

It is worth marking what the verse does not say as much as what it does. It names a quality and three tastes; it does not name a quantity, a dish, or a rule of how much. The dietetic grammar it draws on treats taste as the first reading of a food's action — the doorway through which sweet builds, sour kindles, salt softens and moistens — but it leaves the rest of the calculus (the food's heaviness, its potency, its effect after digestion) to the wider system the chapter is only sketching here. In other words, this is framework, not recipe. The verse tells the reader which direction nourishment should turn in the restoring season — toward the unctuous and the building — and trusts the elaboration that follows, season by season, to supply the particulars. Read this way, snigdha and the three rasa are less a menu than a compass-bearing for the second half of the year.

Where It Sits in Vagbhata's Seasonal Argument

This verse is the mirror image of verse 4, and with it the framework laid out across verses 1 through 6 is complete. Verse 4 named the light, reducing tastes that preserve strength in the fiery depleting arc; this verse names the rich, building tastes that restore strength in the lunar giving-back arc. Set side by side, the two verses make a single teaching: the year's two halves call for opposite kinds of food, because the body's needs reverse as it moves from being drawn down to being filled back up. Between them, the two lists account for all six tastes of the dietetic grammar — bitter, astringent, and pungent for the fiery half; sweet, sour, and salty for the lunar half — so that the year is split cleanly down the middle of the palate.

The word balinaḥ carries the hinge of the whole argument. It returned here from verse 4, but its sense has flipped. In verse 4 "strengthening" meant strengthening by lightening — protecting a depleted system from being overloaded. Here "strengthening" means strengthening by building — refilling a system whose fire can finally bear it. To strengthen in the taking season is to subtract; to strengthen in the giving season is to add. With this distinction the scaffolding is finished. The reader now holds the entire architecture: six seasons grouped into the depleting northern course (ādāna-kāla) and the restoring southern course (visarga-kāla), the cosmic mechanism of solar taking and lunar giving, and the two complementary sets of strengthening tastes that follow from each. Everything that comes after in the chapter — the detailed regimen for each individual season — is elaboration of this frame.

How the Commentary Tradition Reads It

The two standard commentaries on the Aṣṭāṅga Hṛdaya read this close in the same key. Arunadatta's Sarvāṅgasundarā tends to gloss the strengthening tastes by their action on the tissues, treating sweet, sour, and salty as the flavors that increase substance and refill what the dry season depleted, and reading snigdha as the corrective to the accumulated dryness of the northern course. Hemādri's Āyurvedarasāyana tends to set the verse explicitly against verse 4, drawing out the deliberate symmetry by which the six rasa divide between the two halves of the year. Both lines of interpretation agree that the verse is not adding a new rule so much as completing a balance — the restoring counterpart to the reducing counsel that came before. Where they can differ in emphasis is on whether the cool season's strengthened agni or the body's depleted reserves is the primary reason the building tastes now suit; in practice the text holds both, since a strong fire and an empty store are exactly the conjunction that makes rich food both digestible and needed.

Why the Direction Makes Sense

The logic is the accumulation-and-relief logic that governs the whole ādāna and visarga axis. Across the depleting course, dryness, lightness, and heat accumulate while strength is drawn out of the land and the body; the light, clarifying tastes hold the line but cannot refill. When the season turns — when clouds, rain, and cold winds quiet the heat — the conditions that caused the depletion are removed, the fire that summer had scattered gathers in the cool, and only then can the heavy, moistening tastes do their building work without becoming a burden. The richest, most building foods belong to the cold seasons precisely because both the digestive fire and the capacity to use it are then at their height. The symmetry of the two verses is therefore not decorative; it is the practical expression of a single physiological truth, that nourishment must match the body's changing capacity to receive it, and that the season itself tells you which capacity is at hand.

There is a quiet structural elegance worth pausing on, since it is part of why this verse rewards close reading. The two halves of the year, the two courses of the sun, the two lists of strengthening tastes, and the two senses of balinaḥ all map onto each other without remainder: take and give, north and south, reduce and build, subtract and add. A teaching that began with the sun's motion across the sky ends on the surface of the tongue, and the line between them is unbroken. This is the kind of architecture that makes the chapter teachable — a reader who grasps the single axis holds the whole, and the detailed regimens that follow can be hung on it one season at a time. The verse earns its place as the close of the framework not by introducing anything new but by completing a shape, so that what had been an asymmetry — one arc described as taking, the other only implied — becomes a balanced whole the moment the building tastes are named.

The principle this verse rests on — that the cool, moist season is the time to eat richly and rebuild, with the heavy, oily, sweet-sour-salty foods that the hot season could not bear — is among the most cross-culturally robust ideas in all of dietetics. Physicians who never met and shared no vocabulary converged on it, because it tracks something true about how appetite and digestion shift with the cold. Worth keeping in view, though, is that the convergence is on the counsel, not on the physiology: each tradition explains the same advice through its own model of the body and the year.

The Hippocratic Regimen is explicit and close. It counsels heavier, warming, more nourishing food, and more of it, in the cold seasons, when in humoral terms the body's innate heat is drawn inward and concentrated, strengthening digestion — and lighter, cooling food in summer, when that heat disperses to the surface and digestion weakens. That is the same reasoning that sits beneath this verse: the fire summer scattered now gathers in the cool and can handle richness. The Galenic system that grew from those roots organized seasonal eating through the four humors and their qualities, hot and cold, moist and dry, so that the cold-and-wet season of winter was met with foods chosen to warm and the hot season with foods chosen to cool. The Unani tradition that carried Galen into the Arabic and Persian world formalized the same counsel under tadbīr, the management of the six non-naturals, of which air and food and drink are foremost; its regimen prescribes the building, moistening foods for the cold and restricts them in the heat, on a reasoning a reader of this verse would recognize at once.

Chinese dietary medicine arrives at the same place by a different road, through the inward-gathering of yáng across the year. In the Huáng Dì Nèi Jīng's teaching of sì shí yǎng shēng, the nourishing of life across the four seasons, winter is the season of storage — the time to conserve, to keep the warmth gathered within, and to favor warming, tonifying foods that build the reserves one will spend in spring. Because the transforming power of the Spleen and Stomach is held to be strongest when heat is gathered inward, rich food is both better digested and more needed in the cold. The Chinese tradition thus shares with this verse both the timing, that rich food belongs to the cold, and the physiology, that digestion is strongest when heat is concentrated inward — though it routes the whole through the five-phase correspondences and the storing organ of winter rather than through tastes and tissues.

The same seasonal sense runs through traditions that are not strictly medical. Tibetan Sowa Rigpa, itself shaped in part by Āyurvedic transmission, keeps a seasonal conduct in which winter's strong digestive heat is matched with the nourishing, oily, and substantial foods that build the body against the cold, while the lighter seasons call for lighter fare. Monastic horaria across the Christian and Buddhist worlds shifted diet and fast by the season, with the lean, penitential fasts often falling in spring and richer eating clustered in the cold festivals — a rhythm an agrarian society arrived at as much from the harvest calendar as from any theory of the body. What is characteristically Āyurvedic, against all of these, is the precise resolution of the counsel into the six-taste grammar. Where the Greek, Arabic, and Chinese systems speak broadly of heavier, warming, or nourishing food, Vāgbhaṭa keys the rebuilding season to three named tastes — madhura, amla, lavaṇa — and to the quality of snigdha, set in deliberate symmetry against the bitter, astringent, and pungent of the depleting arc. That taste-by-taste symmetry, the year split cleanly down the middle of the palate, is the distinctive shape the Indian tradition gives to a piece of wisdom the ancient world held in common.

It would be too easy to flatten these into one teaching, and the differences are as instructive as the agreements. The Greek and Unani systems hang the counsel on the four humors and the qualities of hot, cold, moist, and dry, so that a food is chosen to correct a seasonal excess of one quality; the Indian system hangs it on the three doṣa and the six tastes, a finer and differently cut grid. The Chinese system locates winter's strength in a storing organ and a phase of the five-phase cycle, where the Indian system locates the restoring season's strength in a strengthened agni and an axis of solar taking and lunar giving. Even the boundary of the seasons differs: where this verse draws its line at the moment the rains break the heat, the European calendar tends to anchor on the solstices and the harvest, and the Chinese on the start-of-season nodes of its solar terms. What is striking is that across such different maps of the body and such different ways of cutting the year, the practical advice converges — eat lighter when the heat scatters the fire, eat richer when the cool gathers it. Convergence on the counsel through divergent reasoning is, if anything, stronger evidence that the counsel tracks something real than agreement on the theory would be, since the traditions are not borrowing from one another so much as each arriving, by its own road, at the same observed turn of appetite and digestion across the year.

Verse 6 completes a teaching that only makes full sense alongside its twin in verse 4: the right kind of nourishment depends entirely on which season you are in. The very foods that would have overwhelmed the depleted system — the rich, the oily, the sweet — are exactly the ones that rebuild it once the conditions have turned. Nothing about the food changed; what changed is the body's capacity to receive it. Richness offered to a depleted system is a burden; the same richness offered to a recovering one is a gift. Beneath the dietetics, this is a claim about porousness — that a living body is not sealed against its surroundings but answers to them, cooling when the land cools, kindling when the heat lifts, so that the same input lands differently depending on the state the season has put the body in.

The opening image carries the first lesson. The building foods are appropriate only after the heat has been quieted — śānta-tāpe, once the clouds and rain and cool winds have done their work. Timing is everything. To begin heavy rebuilding while the depleting conditions still rage is to repeat the error the depleting arc warns against; the rich nourishment must wait until the system has truly cooled and its capacity has returned. The wisdom is in reading the turn correctly — in not rushing to feast while the fire is still scattered, and in not continuing to stint once the season of plenty has genuinely arrived. Cyclical truth is not just knowing the two modes but sensing the moment one gives way to the other.

The deeper teaching is the symmetry of the whole. Across verses 4 and 6 the six tastes divide cleanly: the lightening, clarifying flavors for the season that takes, the building, nourishing flavors for the season that gives. This is a way of meeting any cyclical system with the complementary response rather than a fixed one. There is a time to clarify and reduce and a time to nourish and build, and wisdom consists not in preferring one mode forever but in knowing which the present moment asks for. The one who only ever lightens will waste in the season of plenty; the one who only ever builds will clog and overload in the season of heat. Both modes are right, in their season, and to absolutize either is to fall out of step with the cycle that gives each its meaning.

And there is the quiet dignity the verse grants to richness itself. After lines that prized restraint and lightness, this one fully affirms the heavy, the oily, the sweet — not as indulgence but as the proper medicine of the restoring season. There is a time when fullness is exactly right, when receiving abundantly is not weakness but wisdom, when the body's strongest season can and should be met with its richest nourishment. The verse refuses to make a virtue of permanent austerity. Restraint and abundance each have their hour, and the whole art is to honor both, and to honor the cool counsel that tells you which hour it is.

What gives the teaching its quiet weight is that it does not ask the body to override its surroundings but to move with them. The depleting season is not fought; it is met with lightness so that nothing is lost. The restoring season is not braced against; it is met with fullness so that what was lost is regained. In both halves the response is cooperative rather than willful — read the condition, then answer it in kind. This is the opposite of forcing a single regimen through every season by discipline alone. The verse trusts the cycle to do half the work, and asks of the person only that they not stand against it: that they not feast while the fire is still scattered, and not starve once the season has turned generous. Lived out across a year, this is less a diet than a way of staying in conversation with the world one is part of — porous to it, answerable to it, and at ease in the knowledge that the right response will change because the season changes, and that changing with it is not inconstancy but fidelity to a deeper rhythm.

Verse 6 is the rebuilding half of the chapter's dietary logic, and read broadly it completes a model of matching nourishment to capacity. What follows is educational context drawn from Āyurveda's seasonal dietetics, described rather than prescribed.

1. The cool season as the body's rebuilding window

The classical claim is that once the heat is quieted, the cool, moist season is when the digestive fire gathers and the body can finally take and use rich, building food. Translated to the contemporary calendar, this is the observation that appetite and the appetite for heavier food tend to rise as the year turns cold, and that many people find substantial, warming, oily, and naturally sweet foods — slow-cooked grains and root vegetables, soups and stews, dairy and good fats where they are tolerated — sit better in autumn and winter than they did in high summer. The regimen describes the cold seasons as the place for the heaviest nourishment because both the fire and the body's strength are then highest. Read descriptively, it is an invitation to notice that the same meal can feel nourishing in one season and leaden in another, and that the season is part of why. Contemporary eating tends to flatten the year — the same foods are available and eaten in January and July — and one thing the classical frame offers is simply the question the modern kitchen rarely asks: what does this season itself call for. Many people, asked it, find their own preferences already half-aligned with the answer, reaching for soup and roasted roots as the light fails and for raw, cooling, watery foods as it returns.

2. Matching the load to current capacity

The verse names the rich, oily, sweet-sour-salty foods as strengthening in the restoring arc — the same heaviness that the depleting arc treated as overburdening. The descriptive principle is that the value of any rich input depends on the system's present capacity to absorb it: the same load is a burden to a depleted system and fuel to a recovering one. People convalescing from illness, or coming off a depleting stretch of work or stress, often observe the same thing the text describes — that gentle, building food is welcome and assimilated when capacity has returned, where it would have sat heavily before. The frame suggests reading capacity first and then deciding how much to add, rather than holding to one fixed intake regardless of state. It maps, too, onto domains well past food: resources, intensity, and ambitious commitments all land differently on a system that is depleted versus one that is recovering. A team coming off a punishing quarter, a budget rebuilding after a shock, a person returning from burnout — in each, the same input that would have crushed the system at its low point becomes exactly what restores it once the basic capacity is back. The descriptive observation is that the input is rarely the problem on its own; the readiness to absorb it is the variable, and it is the one most easily overlooked because it is invisible from the outside. The verse's contribution is to make that variable the first thing read rather than the last.

3. Waiting for the turn before rebuilding

The building foods belong only after the heat has been quieted, śānta-tāpe. The lesson is one of timing. Rebuilding begun while the depleting conditions still rage simply repeats the original overload, and the framework counsels confirming that conditions have genuinely shifted from depleting to restoring before ramping investment back up. Equally, it counsels not staying in conservation mode once the restoring season has clearly arrived — the person who keeps fasting into the harvest wastes the plenty. In a contemporary register, this is the wisdom of not loading a body, a schedule, or a budget back to full the moment a hard stretch eases, but also of not staying defensively lean once the strain has genuinely lifted. Reading the turn correctly is the whole skill, and the verse locates that turn in observable conditions — the rain has come, the heat has broken — rather than in the calendar alone.

4. Honoring both reduction and abundance in their season

Across verses 4 and 6 the response splits cleanly: lighten in the taking season, nourish in the giving season. The descriptive value here is in resisting a single fixed posture. Much modern wellness culture leans hard toward one mode — perpetual restriction, or perpetual optimization and addition — and the chapter's symmetry quietly corrects both. A strategy of permanent austerity wastes the seasons of plenty; a strategy of permanent expansion overloads the seasons of strain. Matching the complementary response to the actual phase is the durable principle, and it is one many people recognize in their own felt rhythm across the year — the natural pull toward lighter, fresher food when the days lengthen and toward warm, substantial food when they shorten. The classical system gives that intuition a structure, dividing the year and the palate so that each half has its own work. As a frame — match nourishment to capacity, wait for the turn before rebuilding, and honor reduction and abundance each in their season — verse 6 closes the chapter's architecture with a balance that holds well beyond the plate.
