The short version
Chapter 22 of the Sutrasthana of the Ashtanga Hridaya is called Gandusadi-Vidhi Adhyaya — “the chapter beginning with gandusa”. It gathers six separate practices that share nothing except a location: the mouth, the face, the head and the ears. The interesting thing is not the practices. It is the ruler. Vagbhata gives a quantity for almost everything here, and nearly every quantity is taken from the body of the person in front of him — a fraction of his own mouth, a fraction of his own finger’s breadth, the circumference of his own head, and a unit of time defined as one blink of the eye. Ten measurements in this chapter are body-derived. One is not.

Where Gandusadi-Vidhi Adhyaya Sits in the Ashtanga Hridaya Sutrasthana
The Ashtanga Hridaya of Vagbhata opens with a Sutrasthana of thirty chapters, and the back third of that Sutrasthana is a run of practical chapters, each named for a procedure and each ending in the same formula: thus ends the chapter entitled … composed by Acarya Vagbhata, son of Sri Vaidyapati Simhagupta. They come in a deliberate order. Oleation, then sudation, then the two great evacuations, then the enema, then the nose. Then, at Ashtanga Hridaya, Sutrasthana, chapter 21, the medicated inhalation. And then chapter 22.
Chapter 22 is Gandusadi-Vidhi Adhyaya. The title is built the way Vagbhata builds a great many of his titles — a first item plus -adi, “beginning with”. The commentary in the edition used here makes the point explicitly on the opening page: the word itself tells you the chapter is not only about gandusa. Along with gandusa it covers kavala, pratisarana, alepa, murdha taila and karnapurana. Six practices under one heading, and the heading names only the first of them.
The chapters immediately before it set the pattern. At chapter 13 Vagbhata sorts the ripe from the unripe dosa; at chapter 14 he declares treatment two-fold and then breaks his own pair; at chapter 15 he collects the named drug groups of the Sutrasthana; and at chapter 16 he turns to oleation, the subject Charaka gives a chapter of his own. Each chapter takes one organising idea and exhausts it. Chapter 22 is no different, but its organising idea is easy to miss because it is not stated where you would expect to find it.
That is worth pausing on, because it is a genuinely odd way to organise a book. These six are not variants of one another. Holding a liquid in the mouth, rubbing something onto the inner cheek with a finger, spreading a paste over the face, pouring warm oil onto the scalp and putting drops in the ear are six unrelated actions using different materials and different instruments. There is no shared mechanism. There is no shared indication. Read as a chapter of therapeutics, it looks like a drawer where several unrelated things ended up together.
It is not a drawer. Vagbhata tells you the principle himself, and he does it in the closing line rather than the opening one. The colophon summarises what the chapter has covered and ends by describing all of it as techniques “pertaining to the head region”. That is the organising principle: not the mechanism, not the material, not what any of it is directed at — the place. Everything in chapter 22 happens above the neck.
Once you accept that, the chapter becomes legible, and something much more interesting becomes visible in it. Vagbhata is unusually generous with numbers here. He gives quantities, thicknesses, widths, heights, repetitions and durations, far more densely than in most chapters of comparable length. And when you list those numbers out and ask what each one is measured against, the answer is almost always the same, and it is not a standard.
Gandusa and Kavala: Vagbhata Says the Only Difference Is Movement
Start with the two terms in the chapter’s own title, because they are the pair most often collapsed into one another, and because Vagbhata separates them in a single sentence that leaves no room to argue.
Gandusa is holding the liquid in the buccal cavity for a set period without moving it to and fro. Kavala is holding the liquid in the oral cavity and allowing it to move to and fro. The text then states the distinction outright, in a line that is almost startling in how little it leaves unsaid: moving the substance and not moving it is the only difference between kavala and gandusa.
The whole distinction, in one variable
Same mouth. Same liquid. Same session. Same endpoint. The two practices are separated by one thing and one thing only, and the text names it: whether the liquid is allowed to move. Everything else — what is used, how much, for how long, and when to stop — is shared between them, which is why the chapter goes on to discuss the two together as a single unit and gives them a single set of measures.
This matters for reading the rest of the chapter. Having drawn the line, Vagbhata immediately stops handling them separately. The measures that follow are given for gandusa and kavala jointly. The stopping rule is given for both. The count of repetitions is given for both. He has separated the two just far enough to name them, and then folded them back together because for every purpose except the name they behave identically.
It is also worth noticing what the definition does not depend on. It says nothing about the substance. It says nothing about the quantity. It says nothing about who the practice suits. The two words are defined purely by a mechanical property of what the person does, which is the same style of definition the Sanskrit technical vocabulary uses throughout — a term earns its place by naming a distinction, and the distinction is stated in terms you could verify by watching.
Not millilitres. A half, a third, a quarter of the vessel you already own.
Pravara, Madhyama and Hina Matra: A Measure Taken From Your Own Mouth
Having defined the pair, the text supplies three grades of measure for them, and this is where the chapter starts to become unusual. The three grades are pravara (the largest), madhyama (the middle) and hina (the smallest). Each is stated as a fraction, and the thing being fractioned is not a vessel and not a weight.
| Grade | Sanskrit | The quantity, as the chapter states it |
|---|---|---|
| Largest | Pravara matra | Half the capacity of the buccal cavity |
| Middle | Madhyama matra | One-third the capacity of the oral cavity |
| Smallest | Hina matra | One-fourth the capacity of the oral cavity |
A half, a third and a fourth — of the mouth of the person doing it. Not of a bowl, not of a standard vessel, not of any weight in the classical tables of measure. The quantity is defined by an organ that every reader already has, that varies from person to person, and that requires no equipment whatsoever to calibrate.
The consequence is that the measure travels perfectly. A physician in one region and a physician a thousand miles away, using different vessels and different local weights, will arrive at the same practical quantity because they are both fractioning the same anatomical structure. In a text transmitted by memory and by hand-copy across a subcontinent for centuries, that is not a quaint touch. It is the most robust way available to specify an amount, and Vagbhata uses it deliberately.
It also scales itself. A large adult and a small one are given proportionally different amounts by the same instruction, with no adjustment table and no arithmetic. The measure is self-adjusting because the ruler is the patient.
What the three grades are keyed to
The chapter attaches the grades to the strength and constitution of the person rather than to a fixed schedule: the largest grade for the strong, the middle grade for those of middling build, and the smallest for the delicate and for those of pitta constitution. The grading is by the person, in a chapter whose measures are also taken from the person — the two ideas are the same idea, applied once to the quantity and once to the choice.
Pratisarana and Its Three Forms: Kalka, Rasakriya and Curna
The third practice in the chapter is pratisarana, and its definition is again mechanical rather than therapeutic: applying a substance inside the mouth with the help of a finger. That is the whole definition. The instrument is a finger, and the text names no alternative to it.
What makes pratisarana worth its own section is that Vagbhata immediately splits it by physical form. The same materials used for gandusa can be used here, he says, and they can be presented in three states:
| Form | Sanskrit | What it physically is |
|---|---|---|
| Paste | Kalka | A wet, ground paste |
| Solidified decoction | Rasakriya | A decoction reduced until it sets |
| Powder | Curna | A dry milled powder |
Three states of matter for one action, chosen by texture rather than by content. This is the same instinct that runs through classical Ayurvedic pharmacy generally — the five classical preparations of a herbal extract are likewise distinguished by physical state and not by ingredient, and the wider literature on how classical medicines are made is organised around exactly this axis. Chapter 22 simply applies the general principle to one small site.
The third form is a dry powder, and the instrument named for it is a finger.
The pairing of the powder form with a finger as the applicator is a small detail with a long afterlife. A dry milled powder, taken on a fingertip and worked along the inside of the mouth, is a preparation form that has never gone out of use on the subcontinent, and it is the form in which a great deal of everyday oral practice is still carried out today. The classical vocabulary for it is curna, and Vagbhata’s own chapter on the morning care of the teeth uses the same form and the same instrument.
Note also what is not here. Pratisarana has no measure of its own in fractions of the mouth. Instead it is the one place in the chapter where a weight appears, and that weight is the exception this article is building towards.
Alepa Measured in Angula: The Breadth of a Finger, Divided by Four
The fourth practice is alepa — a paste spread over the face. Vagbhata sorts it into three kinds by what it is meant to do, keys the temperature of the paste to the dominant dosa, and then does something more interesting: he measures its thickness.
The thickness is given as a fraction of an angula. An angula is a finger’s breadth — again, the finger of the person concerned. Three thicknesses are named, at one-fourth, one-third and one-half of an angula. So a paste is specified not in millimetres and not by the amount used, but as a fraction of the width of a finger.
The same trick, one station further up
A liquid in the mouth is measured as a fraction of the mouth. A paste on the face is measured as a fraction of a finger. In both cases the reader supplies the ruler, and in both cases the ruler is attached to the reader. The chapter has now used the device twice, on two entirely different materials, at two different sites.
The removal instruction is equally physical. The paste is left until it dries of its own accord, and it is taken off by moistening rather than by scraping — the drying is the timer. There is no clock anywhere in this passage. The material tells you when it is finished.
Vagbhata devotes the following verses to six named pastes, one for each season of the year, each built from a different short list of plant materials. That seasonal set is a substantial subject on its own and has been covered separately in a dedicated article on Vagbhata’s six seasonal face pastes; this article leaves it there and stays with the measurement question, which is what chapter 22 is unusual for.
Murdha Taila’s Four Rungs: Abhyanga, Pariseka, Picu and Sirovasti
The fifth practice is murdha taila — oil applied to the head. Vagbhata names four kinds, and then says something he says nowhere else in the chapter: these are superior to one another in their succeeding order. Not four alternatives. A declared ladder, in a stated direction.
Which oil is a question chapter 22 leaves to other chapters; Vagbhata’s section on the oils themselves sits much earlier in the Sutrasthana and is where the materials are characterised. Here the material is taken as given and only the manner of application is at issue.
| Rung | Sanskrit | What physically happens |
|---|---|---|
| 1 | Abhyanga | Oil applied and the head massaged gently |
| 2 | Pariseka (also sirahseka) | Warm oil poured in a systematic stream |
| 3 | Picu | A pad of cloth or cotton soaked in oil and kept in place |
| 4 | Sirovasti | Oil held standing on the head inside a fitted retaining band |
Four rungs, and the text says outright that each stands above the one before it.
Read the right-hand column downwards and the ladder explains itself. The variable that increases from rung to rung is the same at every step: how much oil is in contact with the head, and for how long it stays there. A massage puts a film of oil on the scalp for the length of the massage. A pour keeps a moving stream on it. A soaked pad holds a charge of oil against one place continuously. And at the top rung the oil is no longer applied to the head at all — it is impounded on it, standing in a reservoir made by strapping a band around the skull.
So the ordering is not a ranking of prestige or of antiquity. It is a physical quantity, monotonically increasing, and Vagbhata's word for what increases with it is simply that each is superior to the last. The word does the work of a scale.
The point that makes this section worth a careful reading is what happens to the numbers as you climb. At rung one there is no number at all. At rung two there is no number. At rung three there is no number. Every quantity in the entire murdha taila passage is attached to rung four.
Sirovasti: The Only Procedure Here That Gets Both a Clock and a Sign
Sirovasti is where the chapter’s arithmetic concentrates, and it is worth setting out why that is not a coincidence.
Everywhere else in chapter 22, the instruction for when to stop is a sign, not a duration. Gandusa and kavala are continued until the mouth fills or until there is watery discharge from the nose and eyes — the body signals the endpoint. The face paste is left until it dries. Ear drops are retained until the reason for them settles. These are all self-terminating: the person doing them can tell when they are done by looking, and no counting is required.
Sirovasti is the exception. It is given both. It has a sign — it is continued until there is watery discharge from the ears, mouth and nose — and it is also given explicit durations, scaled by the dominant dosa, plus an outer limit in days.
The chapter’s only dosa-scaled clock
The durations run downward across the three dosas — ten thousand, then eight thousand, then six thousand matra kala — and drop to one thousand matra kala for a person who is well. Beyond that there is a hard ceiling in days: the practice is not carried past seven. Nothing else in chapter 22 is fenced this thoroughly.
The pattern is consistent and, once seen, hard to unsee: the more the procedure does, the more the text constrains it. A rinse that stops itself gets a sign and no clock. A reservoir of warm oil standing on someone’s head gets a sign, a dosa-scaled duration, a healthy-person duration, and a maximum number of days past which it is not to run. The numbers are not there because Vagbhata liked numbers. They arrive exactly where the person can no longer be trusted to notice the endpoint on their own.
Even the apparatus is dimensioned, and dimensioned in the same body-derived way as everything else. The retaining band is specified at twelve angula in width — twelve finger-breadths — and its length is not given as a number at all. It is given as the circumference of the patient’s own head. The oil standing inside it is specified at a height of one angula. Three measurements on one piece of apparatus, and all three are relative to the person it is going on.
Twelve fingers wide, and exactly as long as the head it is going around.
What this article deliberately withholds
Chapter 22 gives detailed working procedures for several of these practices, along with the lines describing what each is directed at. None of that is reproduced here. This article carries no dose figures, no preparation sequence, no method you could follow and no indication list. It is a reading of how the chapter measures things, written for people interested in classical texts. It is not clinical instruction and not diagnostic guidance. These are procedures for a trained physician; several of them can do real harm if attempted from a description.
Matra Kala: The Chapter’s Unit of Time Is One Blink of the Eye
All those thousands raise an obvious question, and Vagbhata answers it in the same chapter rather than sending the reader elsewhere. What is a matra kala?
His definition is two alternatives, and both of them are actions of the reader’s own body. One matra kala is the time taken to move one’s right hand once around the right knee joint. Or — and this is the version worth remembering — it is the time taken for one blink of the eye.
A clock with no clock in it
The chapter’s unit of time is not a fraction of a day, not a shadow length, not a measure of water or sand. It is a blink. The instrument is the observer, and it is an instrument nobody can lose, forget to bring, or fail to calibrate. It also has the property that every reader across every century of the text’s transmission has carried an identical copy of it.
Take the definition literally for a moment and the durations acquire a texture that the bare numbers hide. A thousand blinks is not a figure of speech; it is a genuinely short interval, on the order of a quarter of an hour at an unhurried rate. Ten thousand is a long sitting. The scale is coarse — nobody is counting to ten thousand — but it is not arbitrary, and it orders the four cases correctly relative to one another, which is all a scale of this kind is asked to do. That arithmetic is the reader’s own and not the text’s; Vagbhata gives the unit and the counts and stops there.
This is the third distinct use of the same device in one chapter. The mouth measures the volume. The finger measures the thickness and the width. The eyelid measures the time. Vagbhata is not reaching for the body once as a rhetorical flourish. He is using it as the chapter’s entire system of units.
Karnapurana and the Thousand: One Number at Two Different Stations
The sixth and last practice is karnapurana — filling the ear. It gets two sentences. The base of the ear is massaged first, drops are put in, and they are retained either until the reason for them settles or, in a person who is well, up to one thousand matra kala.
That number should look familiar, because it appeared a few verses earlier attached to something else entirely. The duration for sirovasti in a person who is well is also one thousand matra kala.
The healthy person’s number
The two most physically dissimilar practices in the chapter — a leather band holding a standing pool of oil against the skull, and a few drops resting in the ear — are given the same duration when the person is well. Wherever the practice is being done on someone who is not unwell, the figure is a thousand blinks. The dosa-scaled ladder of ten, eight and six thousand applies only away from that baseline.
Whether Vagbhata intends this as a general rule for the healthy or whether it is simply a conventional round figure appearing twice, the text does not say, and it would be overreaching to insist on the stronger reading. It is worth naming rather than smoothing over: two stations, two very different procedures, one shared number, and no statement in the chapter connecting them. Both readings are available, and the chapter does not settle it.
What is not in doubt is that the ear gets the smallest treatment in the chapter. The practices are ordered roughly by how much the text has to say about them, and karnapurana comes last with the fewest words, the fewest constraints and no apparatus at all.
Kola: The One Measurement in the Chapter That Is Not a Body
Now the count, which is the reason this chapter is worth an article.
Set out every quantity in the window under discussion and sort them by what they are measured against. On one side go the body-derived measures. On the other, everything else.
| # | The measurement | Measured against |
|---|---|---|
| 1 | Largest grade for the mouth rinse | Half the buccal cavity |
| 2 | Middle grade | One-third the oral cavity |
| 3 | Smallest grade | One-fourth the oral cavity |
| 4 | Thinnest face paste | One-fourth of an angula |
| 5 | Middle face paste | One-third of an angula |
| 6 | Thickest face paste | One-half of an angula |
| 7 | Width of the retaining band | Twelve angula |
| 8 | Length of the retaining band | The circumference of the patient’s own head |
| 9 | Height of the standing oil | One angula |
| 10 | The unit of time itself | One blink of the eye, or one turn of the hand about the knee |
Ten measurements, and every one of them is a fraction, a multiple or a function of the body of the person the procedure is being done to. Volume, thickness, width, length, height and time — six different dimensions, all pegged to the same ruler.
And then there is the exception. In the passage on pratisarana, where the substance is a paste rather than a liquid, the amount is given as one kola — the weight of a single jujube seed. That is a unit from the standard classical tables of weight. It is not a fraction of anything the person owns. It is a seed, and it is the same seed for everybody.
One seed. The only measurement in the chapter that is not part of you.
Ten from the body, one from a seed
Exactly one quantity in this chapter is defined by an object external to the patient, and it is the only one that had to be. A paste has no natural container in the mouth the way a liquid does — you cannot specify a paste as a fraction of the cavity it is being rubbed into, because it is not filling the cavity. So the moment the material stops being pourable, the body stops working as a ruler and Vagbhata reaches for a weight. The exception is not a lapse. It is the boundary of the method, and it shows up exactly where the method runs out.
Two further figures deserve naming rather than folding into the thesis, because they belong to neither column. The repetitions of the mouth rinse are given as three or five or seven, and the outer limit on sirovasti is likewise given in a small odd number of days. Those are bare counts. They are not measured against the body and they are not measured against an external standard — they are just integers, and a day is a solar unit that has nothing to do with the patient. The honest statement of the pattern is therefore narrower and stronger than the sweeping one: every dimensional quantity in chapter 22 — volume, thickness, width, length, height, duration-within-a-session — is taken from the patient’s body, with a single exception which is a weight; the plain counts and the day-limits stand outside the system altogether.
Six Practices, One Organising Principle: Everything Above the Neck
Step back and the chapter's shape is finally clear, and it explains the title.
Vagbhata is not building a chapter around a mechanism, the way the chapter on the enema is built around one, or around a route, the way the chapter on nasal administration is. He is building it around a region, and then working through that region station by station:
| Station | Practice | Material state |
|---|---|---|
| Mouth — held still | Gandusa | Liquid |
| Mouth — moved | Kavala | Liquid |
| Mouth — rubbed on | Pratisarana | Paste, set decoction or powder |
| Face | Alepa | Paste |
| Head | Murdha taila | Oil, in four increasing degrees |
| Ear | Karnapurana | Oil, as drops |
The chapters on either side confirm the reading. Chapter 21 immediately before is the medicated inhalation — the mouth and nose again. Chapter 23 immediately after is ascotana and anjana, the eye. Chapter 24 continues with further practices for the eye. Vagbhata is moving through the head in a run of chapters, and chapter 22 is simply the stretch of that run covering the mouth, face, scalp and ears, with the eye held back for its own chapters because there is more to say about it.
This is the same compositional habit visible across his Sutrasthana. Vagbhata groups by whatever gives the tightest bundle, and he is willing to change the grouping principle from chapter to chapter to get it. Elsewhere he groups by material, elsewhere by procedure. Here he groups by anatomy, and signals it by naming the chapter after its first member and letting -adi carry the rest.
Why the closing summary is worth reading first
In this chapter the colophon is more informative than the opening. The opening tells you which six practices are covered; the colophon tells you why they are together. With several of Vagbhata’s chapters the same trick works — the last paragraph names the principle that the first paragraph only illustrates.
It is worth adding that this way of describing the head has an older pedigree. The Charaka Samhita already places mouth rinsing and ear oiling inside the daily regimen at Charaka Samhita, Sutrasthana, chapter 5 — the same material that reaches Vagbhata as the morning routine of the dinacharya chapters — and the Sushruta Samhita gathers the mouth practices with inhalation and nasal administration in Sushruta Samhita, Chikitsa Sthana, chapter 40. Vagbhata’s contribution in Ashtanga Hridaya, Sutrasthana, chapter 22 is not the material. It is the compression — and the ruler.
The temperature rules scattered through the chapter point the same way. The face paste is to be warm where vata or kapha dominates and cold where pitta does; the choice of grade for the mouth is keyed to build and constitution. Anyone who has read Vagbhata on the three dosas will recognise the move. What is distinctive about chapter 22 is not that it keys choices to the person — the whole corpus does that — but that it keys the units to the person as well.
Curna, Taila and Lepa: Where a Modern Shelf Sits on This Map
Chapter 22 is a map of stations above the neck, and each station is defined by a physical form: a liquid held in the mouth, a powder worked along it with a finger, a paste spread on the face and left to dry, an oil put on the head. Set a modern shelf against that map and the placement is a question of form and site, nothing more. What follows names materials and places, and makes no claim about outcomes.
The powder station — curna, the mouth
The third of pratisarana’s three forms is a dry milled powder, taken on a finger. Our Ayurvedic Dantmanjan is that form: a dry powder, built on neem and babool, with rock salt, clove and turmeric among its materials. Powder, finger, mouth — the same three things the chapter names.
★★★★☆
“Yes Its herbal and ayurvedic no doubt. Have a question why don’t you grind it a little more finely?”
— swapnil r., verified buyer, Ayurvedic Dantmanjan
A question about the grind is the right question to ask of a curna. Fineness is the property that separates the three forms in the chapter’s own table, and it is the one a buyer can judge by hand.
The oil station — taila, the head
The first rung of murdha taila is oil put on the head. Our Kesh Sanvardhan Tel is a taila made by the classical taila paka vidhi route, with bhringraj and amla carried into a cold-pressed coconut base. Oil, head — the chapter’s first rung and nothing beyond it.
The paste station — lepa, the face
An alepa is spread on, left until it dries of itself, and taken off by moistening. Our Multani Mitti Ubtan is that form: a clay-based paste built on multani mitti with coconut and neem among its materials, applied and removed the same way.
The station we have nothing for
Chapter 22’s sixth station is the ear, and there is nothing on our shelf that belongs there. Karnapurana is a physician’s procedure, not a shelf item, and the honest thing to do with an empty station on the map is to leave it empty rather than to find something to put in it.

Questions People Ask About Sutrasthana Chapter 22
What is the difference between gandusha and kavala? +
Movement, and the Ashtanga Hridaya says so in as many words. In gandusa the liquid is held in the mouth without being moved to and fro; in kavala it is allowed to move. The text states that moving it and not moving it is the only difference between the two. Everything else about them — the measures, the stopping sign, the number of repetitions — is given for the pair jointly.
What is Gandusadi-Vidhi Adhyaya about? +
It is chapter 22 of the Sutrasthana of the Ashtanga Hridaya, and it covers six practices: gandusa and kavala for the mouth, pratisarana applied inside the mouth with a finger, alepa spread on the face, murdha taila for the head and karnapurana for the ears. The name means “beginning with gandusa”, which is Vagbhata’s usual way of titling a chapter after its first item.
Why are six unrelated practices in one chapter? +
Because they share a location rather than a mechanism. The chapter’s closing summary describes all of them as techniques pertaining to the head region. Vagbhata is working through the area above the neck station by station — mouth, face, head, ear — and the eye is held back for the two chapters that follow.
What is a matra kala? +
It is the chapter’s unit of time, and Vagbhata defines it inside chapter 22 rather than elsewhere. One matra kala is the time taken to move the right hand once around the right knee, or the time taken for one blink of the eye. It is a unit every reader carries with them and none can mislay.
What are pravara, madhyama and hina matra? +
They are the three grades of quantity for the mouth practices: the largest is half the capacity of the buccal cavity, the middle is one-third and the smallest is one-fourth. The quantity is a fraction of the person’s own mouth rather than any fixed vessel or weight, which is what makes the measure travel unchanged from one reader to another.
What are the three forms of pratisarana? +
Kalka, a ground paste; rasakriya, a decoction reduced until it sets; and curna, a dry milled powder. The same materials can be presented in any of the three, so the distinction is one of physical state rather than of content. The applicator named for all three is a finger.
What are the four types of murdha taila? +
Abhyanga, pariseka, picu and sirovasti, and the text says they are superior to one another in their succeeding order. Reading them in order, the quantity that increases at each step is how much oil is in contact with the head and how long it stays there — from a film during a massage, to a poured stream, to a soaked pad, to oil standing inside a retaining band.
Is an angula a fixed measurement? +
An angula is a finger’s breadth, so it varies with the person. In chapter 22 it is used for the thickness of the face paste in fractions of a quarter, a third and a half, for the width of the retaining band at twelve angula, and for the height of the standing oil at one angula. Like the mouth and the eyelid, it is a ruler attached to the reader.
Why does sirovasti get numbers when the other practices do not? +
Because it is the only one that does not stop itself. The other practices end on a sign the person can observe — the paste dries, the mouth fills, there is watery discharge from the nose and eyes. Sirovasti is given a sign as well, but also dosa-scaled durations in matra kala and a hard outer limit in days. In this chapter the numbers arrive exactly where the endpoint is no longer self-evident.
Which measurement in the chapter is not taken from the body? +
One: the paste amount for pratisarana, given as one kola — the weight of a single jujube seed, from the standard classical tables of weight. Ten other measurements in the chapter are fractions, multiples or functions of the patient’s own mouth, finger, head or eyelid. The plain repetition counts and the limit in days belong to neither group.
Does this article tell me how to do any of these practices? +
No, and that is deliberate. Chapter 22 carries working procedures and the lines describing what each practice is directed at, and this article reproduces none of it — no dose figures, no method and no indication list. It is a reading of how the chapter measures things, for readers interested in classical Ayurvedic literature. It is not clinical instruction and not diagnostic guidance; these are procedures for a trained physician.
