Ascotana and Anjana in Ashtanga Hridaya Sutrasthana 23: The Chapter Vagbhata Wrote Almost Entirely in the Negative

Ascotana and Anjana: What Sutrasthana 23 Sets Out to Specify

The Ashtanga Hridaya is the youngest of the three texts that Ayurvedic tradition calls the Brihat Trayi, the great triad, and it is the one most often described as the tidiest. Vagbhata inherited the material of the Charaka Samhita and the Sushruta Samhita and compressed it. Where his predecessors argue, he states. Where they wander, he lists. The colophon of the chapter we are reading names him plainly: Acarya Vagbhata, son of Sri Vaidyapati Simhagupta.

Its Sutrasthana — the first of the six divisions — runs to thirty chapters and works outward from principle to practice. By the low twenties it has arrived at a run of chapters on what the tradition calls vidhi, method: how a thing is done. Chapter 22 is Gandusadi-vidhi, and we have read that one already. Chapter 23 is the subject here. Its own opening sentence places it: after Gandusadi-vidhi, Acarya Vagbhata expounded the chapter Ascotana-Anjana-vidhi.

Two words carry the chapter. Ascotana is the pouring of a prepared liquid, drop by drop. Anjana is a collyrium — a prepared substance applied along the inner margin of the lid, the ancestor of what much of India still calls kajal. A third word, bidalaka, appears in passing for the same materials worked into a paste and laid on the outside of the lids instead. All three are procedures. None of them is a substance, a formula or a diagnosis, and this chapter is not the place where the text discusses what any of them is for. That material sits elsewhere in the tradition — most fully in the Uttara Tantra of the Sushruta Samhita, which we have covered in its own right in our articles on Sushruta's therapies of the eye and on Sushruta's account of collyrium, and in our wider survey of what the Sushruta Samhita says on the subject. Vagbhata's chapter here is a different thing from all of those: not an account of what is done and why, but a specification of how it is to be kept within bounds.

What chapter 23 is, is a specification. It is Vagbhata telling a practitioner he will never meet, in a room he will never enter, how to keep an operation inside its limits. And the way he does that is the reason this chapter is worth a long look.

A region defined only by its edges.

Specification by Prohibition: The Shape of Vagbhata's Twenty-Third Chapter

Take the chapter apart by the kind of sentence each part contains, and something odd emerges. A surprisingly small share of it says do this. A very large share of it says not this, and not that either.

There is a prohibition on the hours at which ascotana may be undertaken. There is a set of six faults the poured substance may carry, each one with a stated consequence. There is a rule that anjana is not to be undertaken while the dosas are in an increased state. There is a prohibition on the times of day for anjana, and a second, narrower prohibition for the strong variety, tikshnanjana. There is a prohibition on strong collyrium even at night under certain weather. There is a long list of occasions when the procedure is refused outright. There is a run of paired faults of the material itself. There is a prohibition on blinking, pressing and washing immediately afterwards. And there is a statement of what goes wrong if the washing that comes later is neglected.

Set against that, the positive instructions are few, brief, and mostly concern posture and sequence. The chapter's centre of gravity is not the act. It is the boundary around the act.

That is a real design decision, and it is not the only one available. A text can specify a procedure by describing the ideal and trusting the reader to approximate it. Vagbhata's own chapter 22 largely does that, as we will see. Chapter 23 does the opposite, and the difference is instructive about what the compiler thought was actually at risk.

Ativirya, Atyushna, Atishita: The Six Ways Ascotana Is Said to Go Wrong

The first place the negative grammar shows itself is in the ascotana section, at the verse the translation heads Contraindications — Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 6. The poured substance, the text says, should not be any of the following: too strong, too hot, too cold, excessive in quantity, insufficient in quantity, or such that it stays in one place without spreading.

Six faults. Read the list as a list and its structure appears at once. They are not six unrelated mistakes. They are three axes, each with two ends, plus one:

And then the text does something that a bare list of prohibitions would not need to do. For each fault it names what follows from it. Too strong and too hot have their own consequence. Too cold has a different one. Excessive quantity has a third. Insufficient quantity has a fourth — and the consequence of doing too little is explicitly not simply that nothing happens.

We are deliberately not reproducing those four consequences here, for reasons set out in the section on what this article withholds. What matters for reading the chapter is that they exist and that they are different from one another. Vagbhata is not saying “get it wrong and it will not work”. He is saying that each direction of error has its own signature, and that the signatures are distinguishable.

Too much and too little, named together.

The Paired Opposites of Verse 25: A Target Named Only by Its Fences

If verse 6 hints at the pattern, verse 25 states it outright. Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 25 lists the qualities a collyrium must not have, and the translation renders them as a run of matched pairs: too strong or too mild in potency; too little or too much in quantity; too thin or too thick in consistency; too rough; too cold or too hot.

Count what is being done there. Four properties — potency, quantity, consistency, temperature — and for three of them the text gives both failure directions in the same breath. Roughness stands alone, as distribution did in verse 6.

And at no point does the verse say what the potency, the quantity, the consistency or the temperature should be. There is no target value anywhere in the sentence. The acceptable region is defined entirely by its edges.

The second is what a text does when it knows it will be read a long way from where it was written. The Ashtanga Hridaya was compiled to be memorised and carried. A bracket travels; a target does not. Seen that way, the negative grammar of chapter 23 is not caution or vagueness. It is a transmission strategy.

It is worth noting that this is a habit of the text and not a one-off. The same compiler builds his account of the routes of illness in Sutrasthana 12 out of divisions and sub-divisions rather than a single ideal, and his two-fold scheme of measures in Sutrasthana 14 is explicitly a pair of opposed directions with the correct position lying between them.

The Refusal List: Anjana Withheld From the Person, Not From the Part

The longest single passage of prohibition in the chapter is at Ashtanga Hridaya, Sutrasthana, Chapter 23, verses 23 to 24. It is a list of occasions on which anjana is not to be undertaken at all.

Go through it and sort the entries by what kind of thing each one is. The result is the most striking feature of the whole chapter.

Look at what is not on that list. Almost nothing on it concerns the part being worked on. A person who is frightened, or angry, or grieving, or who has just eaten, or who is holding an urge, or who slept badly, or who is thirsty, or who is out in the heat, or who has had a drink — none of those is a condition of the part. They are conditions of the whole person. A couple of bodily states do appear in the verse alongside them, and we are not reproducing those; but they are a minority of the list, and the shape of the majority is unmistakable.

And one entry is not a condition of the person either. A day without sunshine. The procedure is refused on grounds of the weather.

This is the ordinary working assumption of the classical texts rather than a claim peculiar to Vagbhata. It is the same assumption behind the doctrine of the three dosas, which we set out in our guide to tridosha in the Ashtanga Hridaya, and the same one behind the classical habit of asking about season and time of day before anything else. What is unusual is to see it applied so bluntly, and in a chapter about a procedure this small.

Some days the answer is simply no.

Pratyanjana: The Chapter Ships Its Own Undo

Now the feature that, to a modern reader, is the most surprising thing in the chapter.

Vagbhata names a move whose entire purpose is to counter a previous move of his own. It is called pratyanjana, and the word says so: prati-, against or in return, plus anjana. The counter-collyrium.

It appears twice. It is introduced at Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 11, where the translation explains that this is a milder class of collyrium used after a strong one has been applied, and that this is where the name comes from. It returns at verse 31, at the end of the procedural sequence, where it is given with cold substances for the case where the strong collyrium has gone too far.

Two things about that are worth sitting with.

First, it is a named category, not an improvisation. The chapter does not say “if it goes wrong, do something soothing”. It gives the corrective its own term, tells you which of the three classes of anjana supplies it, and gives it a place in the sequence. The undo is part of the specification.

Second, its existence is an admission. You do not build a counter-move into a procedure unless you expect the procedure to overshoot sometimes — not through carelessness, but in ordinary competent use. The chapter that spends most of its length telling you how not to overdo it also assumes, quite calmly, that you will occasionally overdo it anyway, and provides for that case by name.

Anjana Salaka: Five Applicators, and the Text Ranks the Unmade One First

At Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 13 the chapter turns to the instrument. The applicator is called an anjana salaka — a collyrium rod — and the text says there are five kinds.

Four of them are materials: gold, silver, copper, iron. Each is assigned to one of the classes of anjana the chapter has just distinguished. That assignment is classical pharmacological reasoning about metals and we are not reproducing which goes with which, because the classes are defined in the source by what they are for.

The fifth is the index finger.

And the text then states that the index finger is the best one among all the five.

It is easy to read that as folksy. It is better read as a statement about control. Of the five, one is the only one that reports back. A rod transmits pressure without registering it; a fingertip registers what it is doing while it is doing it. In a chapter that is preoccupied from beginning to end with not going too far, ranking the sensing instrument above the four insensible ones is exactly consistent.

The chapter is equally particular about the other object in the room, the gharsana sila — the stone on which the collyrium material is rubbed down. It is specified as smooth, round, and concave in shape, and the reason given for the concavity is simply that the material should not spill. Dimensions are given as well, which we are not reproducing. But note the form of that sentence too: the shape is justified by naming the failure it rules out. Even the furniture of the procedure is specified negatively.

Smooth, blunt, and nothing more than that.

Pinda, Rasakriya, Curna: The Three Forms and Their Declared Order

Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 14 classifies anjana a second time — not by what it is for, but by the physical state it is prepared in. This is the classical idea of kalpana: the same material, delivered as a different kind of thing.

• Pinda — a bolus or pill; a solid mass.
• Rasakriya — a thick liquid, an extract reduced down to a semi-solid.
• Curna — a powder.

The verse then does something the earlier classifications did not: it puts them in a declared order. The text says these are superior to one another in their preceding order, and matches them, in that order, to conditions the chapter grades from severe down to mild. We are not reproducing that matching. What is worth noting is the mechanism, because it is the same one Vagbhata uses in chapter 22 for the ladder of oil applications to the head: a set of forms, an explicit statement that they rank, and the ranking then carrying the weight instead of a number.

Quantities are given for each form at verse 15, and they are measured against ordinary small objects rather than against any absolute unit. We are not reproducing those figures. The method of measuring is the same one we found running through the previous chapter, where almost every quantity is expressed as a fraction of the patient's own body rather than as a weight. Chapter 23 reaches for seeds and for the rod itself. Neither chapter reaches for a scale.

Tejas Sharpens and Blunts: The Simile That Carries the Argument

At Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 21 the chapter stops specifying for a moment and offers an image instead. The translation gives it as: metals are born from stones, and they attain their sharpness as well as their bluntness from those same stones. In the same way, the eyes are tejatmaka — of the nature of tejas, the fiery element — and they receive both benefit and disadvantage from that same tejas, according to whether it is used properly or improperly.

Read that carefully, because it is the thesis of the entire chapter compressed into one comparison.

A blade is put to the stone and comes away sharp. Leave it on the stone and it comes away blunt. The stone did not change. The blade did not change. The only variable is how much. Same agent, same contact, opposite outcomes — and what separates them is not the identity of the thing applied but the degree of its application.

The tejas framing also explains why the chapter is so preoccupied with light and heat. If the part in question is of the nature of the fiery element, then sunlight, midday, a cloudless sky, a sunless day and the cool of the night are not incidental scene-setting. They are further quantities of the same thing. Vagbhata's timing rules and his material rules are, on this reading, rules about one variable.

One stone, and the wear runs both ways.

Samyak Lakshana: Correctness Defined as the Absence of Complaint

Near the close of the chapter, after the washing and the wiping and the counter-move, the text gives what the tradition calls samyak lakshana — the proper signs, the marks by which a correctly performed procedure is recognised. There are three.

The first is relief from what was complained of. The second and third are the ones worth pausing on.

• Not having any discomfort while closing and opening the lids.
• Not having any problem with sunlight and breeze.

Both are stated as negatives. Neither describes a positive sensation of any kind. There is no brightness, no lightness, no pleasant coolness, no sense of wellbeing. The marks of success are the disappearance of friction with ordinary things: the lid moving without being noticed, the sun and the wind ceasing to be an event.

That closes the loop with everything else in the chapter. A text that specifies by naming errors will naturally define success as the absence of those errors. The negative grammar runs all the way from the first prohibition to the last line of the assessment.

Where Vagbhata Records a Disagreement and Leaves It Open

One more feature, easy to skim past. At Ashtanga Hridaya, Sutrasthana, Chapter 23, verse 18 the text reports that some other scholars opine that the strong variety of collyrium should not be applied at midday, and gives their reasoning.

Vagbhata does not adjudicate. He states the position, attributes it to others, gives their argument, and moves on to the next topic. The dissent is left standing in the text.

This is a recognised feature of the classical scientific literature and it has its own technical vocabulary. The Sushruta Samhita devotes a whole late chapter to the devices by which a treatise is constructed — we have written about those thirty-two tantra yuktis — and several of them concern exactly this: how to cite another view, how to mark an opinion as belonging to someone else, how to leave a matter undecided on purpose.

For a reader trying to judge how much weight to give a classical passage, a recorded and unresolved disagreement is a useful signal. It indicates a compiler reporting a live discussion rather than presenting a settled tradition as though it had never been argued about.

Chapter 22 Beside Chapter 23: One Author, Two Opposite Styles of Specification

The clearest way to see what is distinctive about chapter 23 is to set it against the chapter immediately before it, which the same compiler wrote and which the text itself names as its predecessor.

Same author, same division of the same book, adjacent chapters — and two opposite specification styles. That difference is not stylistic drift. The obvious reading is that it tracks how much room for error the subject allows. A rinse held in the mouth can be got wrong and spat out. The subject of chapter 23 cannot. Where the margin narrows, Vagbhata stops describing the target and starts fencing it.

An order declared, not measured.

How We Read and Cite This Chapter

A short note on method, because it affects what we have and have not claimed above.

Our source is an English translation of the Sutrasthana of the Ashtanga Hridaya with the Sanskrit printed alongside. In the copy we worked from, the Devanagari of this chapter is badly degraded — the scan is legible as English but the Sanskrit lines are broken up by the optical character recognition into fragments that cannot be reliably reassembled.

That produces a firm rule, and it is the same one we adopted for the scanned Bhavaprakasha in our article on Sandhi Sharira: we do not quote transliterated Sanskrit from a degraded scan. Every Sanskrit term used in this article — ascotana, anjana, bidalaka, pratyanjana, salaka, pinda, rasakriya, curna, tikshnanjana, gharsana sila, samyak lakshana, tejas and tejatmaka — is taken from the translator's own running English text, where it is spelled out in the Latin alphabet, and not reconstructed by us from the Devanagari.

Verse numbers are a second question. The verse markers in this edition are printed in the margins beside the passages and are legible. Where we have cited a specific verse above — 6, 11, 13, 14, 15, 18, 21, 23 to 24, 25, 31 — the marker sits directly against the passage described. Where we were not confident of a marker we have cited the chapter as a whole instead. We have not invented a single verse number, and where the printed number was ambiguous we said “the chapter” rather than guess.

What This Article Withholds, and Why

We have said several times above that we are not reproducing something. Here is the complete list, in one place, so that a reader can see the shape of the omission rather than discovering it piecemeal.

This article does not reproduce:

• The pouring height and the drop count specified for ascotana.
• The quantity figures given at verse 15 for each of the three forms.
• The dimensions given for the gharsana sila and for the rods.
• The temperature rule that varies the poured substance by dosa.
• The consequences named for each of the six faults of verse 6.
• Which class of anjana is matched to which metal of rod, and which is matched to which condition.
• Any part of the sequence of handling — the positioning, the lid, the rod, the movement afterwards, the washing, the wiping.
• The post-procedural measures given for the different dosa predominances.

The reason is straightforward. No dose figures, no sequence and no indication belong on a public page written for general readers. This chapter describes procedures performed on one of the most delicate structures there is, by a practitioner, with prepared materials, on a person who has been assessed first. Reproducing the operational content of a classical surgical-adjacent chapter as a web article would be irresponsible regardless of how the surrounding sentences were worded.

Nothing is lost from the argument by leaving them out, because the argument of this article is not about what the numbers are. It is about the form the specification takes — brackets rather than targets, refusals rather than instructions, a named undo, and success defined as an absence. Every one of those observations can be made, and checked against the text, without a single operational figure.

Kalpana and the Hand: Our Own Shelf, Named by Form Only

A note before the three items below, and it is a real one rather than a formality. Nothing here relates to the subject matter of the sections above. The chapter we have been reading concerns procedures we do not sell, cannot sell, and would not write a product note about. There is no item on our shelf that belongs anywhere near it, and we are not going to manufacture a connection where none exists.

What we can honestly carry across is one idea, and only one: kalpana, the classical notion of form. Verse 14 sorted its subject into a solid, a semi-solid and a powder — matter and physical state, nothing else. The second idea is the one from verse 13: of the applicators the chapter lists, it puts the bare index finger first. Powder, oil and paste are the three everyday forms that are carried to a surface by the hand and by nothing else.

So the three items below are placed by form and by how they are applied, and by nothing else. What each one is made of, and what physical state it arrives in. Nothing below is a claim of any kind. No property, no outcome, no purpose.

That is the whole of the bridge, and it is deliberately thin. Three classical words for three physical states, and a hand. Nothing on our shelf corresponds to what this chapter is actually about, and a classification of forms is not a shopping list.
