Dhatu Mala and Ojas in the Bhavaprakasha: What Every Tissue Throws Away, and the One Round That Throws Away Nothing

📖 22 min read · Classical source: Bhavaprakasha of Bhavamisra, Purva Khanda, Dhatu Prakarana — the dhatu-mala and ojas passage, printed pages 105–112 of the Hindi-commentary edition (PDF pp.161–168)

The Source: Where the Chain Stops Building and Starts Discarding

The Bhavaprakasha was compiled by Bhavamisra in the sixteenth century, the youngest of the three works grouped as the Laghu Trayi. Its Purva Khanda contains a long section called the Dhatu Prakarana, and the part usually quoted is the part about building: how rasa becomes rakta, rakta becomes mamsa, and so on down the familiar seven — rasa, rakta, mamsa, meda, asthi, majja, shukra.

Those pages are read closely in our article on dhatu poshana and the kedari-kulya verse, which covers the irrigation-channel simile, the dhatvagni or tissue-fires, and the clock that governs each round. This article picks up exactly where that one stopped — in the middle of a sentence, as it happens.

The page that closed the earlier passage ends on the mamsa round: tato māṃsāgninā punaḥ pacyamānaḥ pañcāhorātrāt sārdha-daṇḍaṃ ca yāvan māṃsasy eva tiṣṭhati, tataḥ pacyamānāt tasmān malaṃ nirgacchati — "then, cooked again by the mamsa-fire, it remains in the mamsa for five days and nights and a danda and a half; then, from that cooking, the mala comes out." There the page stops. The next page opens by telling you where that mala goes.

That is this article's subject: not the seven dhatus, nor the mechanism by which one feeds the next, but the other half of the process — the dhatu mala, the leavings. Six rounds, six leavings, each given a destination. Then a seventh round that breaks the pattern completely.

Named roads: dhamani, sira, srotas.

Vyana Vayu, the Courier That Carries Every Mala

Nothing here moves by itself. Every mala is prerita — impelled, driven — and the thing that impels it is always the same: Vyana Vayu.

Vyana is the subdivision of vata whose assigned job is circulation throughout the body rather than movement in one direction. In this passage it works as a courier service: it collects what the previous round left over and delivers it to a named address along a named road.

The roads have names too. Dhamani and sira are the larger vessels; śirā-mārga, the sira-road, is used when something is travelling to the surface. Srotas is the channel proper. And for one destination the text names something far smaller: the loma-kupa, the hair-pit or follicle.

This changes what the dhatu-mala doctrine actually is. Read as a bare list — kapha is rasa's mala, pitta is rakta's, sweat is meda's — it looks like a table of correspondences, the kind of tidy symmetry a sceptical reader is right to discount. Read as it is written here, it is not a table at all. It is a delivery network, with a carrier, a route and a terminus specified for each item.

Mamsa Mala: The Sentence That Runs Across the Page Break

The mala of mamsa, muscle tissue, arrives mid-sentence. The previous page said the mala comes out; this page says where it goes. Driven by Vyana Vayu, it travels swiftly to the ears (karṇau) and becomes the wax of the ears. The Hindi commentary glosses it without ceremony: vaha mala vyāna-vāyu ke dvārā śīghra kānoṃ meṃ jākar kānoṃ kā mail ho jātā hai.

In the older scheme this is kha-mala, the waste of the orifices — khesu malah, glossed in the commentaries as karṇādi-sroto-malaḥ, the discharge of the ear-passages and the rest. Sushruta's verse-list, which the Bhavaprakasha quotes a few pages earlier and which is discussed in our article on the poshana verses, compresses the whole set into a line. What the running prose adds is the delivery — not merely that ear-wax belongs to mamsa, but that Vyana Vayu takes it there, and quickly.

Every round leaves something behind.

Meda Mala: Sweat, and the Only Mala Explained Twice

After the mamsa round the sthula portion travels to the seat of meda, the fatty tissue, which the text places in the udara, the abdomen. There the medo-agni cooks it for the usual five days and a danda and a half. Then the mala comes out, and the text names it: prasveda-rūpaḥ, in the form of sweat.

Here the passage does something it does nowhere else. Having named the mala, it does not move on. It stops and explains the mechanism, at a level of detail it grants no other item:

The likely reason is that sweat is the one mala whose behaviour a person can watch changing in real time: it is not there and then is, heat produces it and cold suppresses it, and it emerges from the skin's surface rather than from an opening. Every step of the description is a step you can check. It reads like a passage written by someone reasoning from what they had watched rather than from what they had inherited — the opposite of the ear-wax clause on the page before.

Asthi Mala: Nails and Body Hair as the Leavings of Bone

From meda the sthula portion is carried through the dhamanis and siras to the asthi, the bones. The asthi-fire cooks it for five days and a danda and a half. The mala comes out, and Vyana Vayu carries it along the sira-roads to the fingers, where it becomes nakha, nails, and loma, body hair.

Of all the pairings in this scheme this is the one a modern reader finds least objectionable, and it is worth being honest about why. Nails and hair are hard, pale, and grow continuously outward from a fixed base — the two structures that most resemble bone in the hand. An anatomist working without a microscope would reach for exactly this grouping. It is a classification by shared properties, and a reasonable one on the evidence available.

Asthi's leavings, and majja's.

Majja Mala: The Eye's Discharge and the Eye's Own Oil

From asthi the sthula portion travels by the srotas to the seats of majja, the marrow, which the text locates inside the large bones. The majja-fire cooks it for the same period. Then the mala emerges and Vyana Vayu carries it by the sira-roads to the eyes, where it becomes two things: netra-viṭ, the discharge of the eyes, and cakṣuḥ-sneha, the oiliness of the eye.

This is the entry that repays attention, because it is the only one where a single mala is assigned two outcomes of visibly different kinds. One is a leaving in the ordinary sense — the crust at the corner of the eye. The other is not a leaving at all: cakṣuḥ-sneha is the eye's own lubrication, the film that keeps the surface wet and moving.

The scheme puts both in one box and derives both from one round of cooking. On its own terms the distinction between the useful product and the useless one does not arise: both are what remains once the majja-fire has taken what it needs, and what remains is sneha, unctuous matter. Whether a portion ends up lubricating the eye or drying at its corner is a question about where it settles, not what it is.

"Iti Eke": Where the Text Records a Disagreement

Tucked into the meda section is a clause easy to read past. After naming sweat as meda's mala, the text adds that the residue of the tongue, teeth, armpits and genitals — jihvā-danta-kakṣā-medhrādi malaḥ — is also meda's mala, iti eke: "so say some."

Iti eke is a stock phrase doing a specific job. It means the compiler is aware of a position, is recording it, and is declining to endorse it — the classical equivalent of a footnote reading "others hold otherwise."

The disagreement is real. Those four sites all produce a residue at the body's surface. On one view they belong with sweat under meda, because meda is the surface tissue; on the other they belong with ear-wax under mamsa, because mamsa owns the openings. Both readings are defensible from the same list, and the compiler leaves the boundary unresolved rather than picking one and printing it as settled.

The Routing Table: Vehicle, Channel, Destination

Set side by side, the rounds on these pages look like this. The right-hand columns are what a bare list of correspondences leaves out.

Two things stand out. The monotony of the vehicle column — Vyana Vayu every time, without exception, which makes it the busiest agent in this stretch of text. And the last row.

Shukra: The One Round That Yields No Mala At All

From majja the sthula portion is carried through the dhamanis and siras to the seat of shukra. The text specifies that seat in a way it has not done for any other dhatu: śukrasya sthānaṃ sakalaṃ śarīraṃ — the seat of shukra is the whole body. Meda had the abdomen; majja had the insides of the large bones; shukra has everywhere. Arriving, the incoming material mixes with the shukra already constituting the body.

Then the shukra-fire cooks it. And the second move of the formula — which has happened without fail at every previous round — does not happen:

It is a surprising claim, and the text seems to know it. Everywhere else the passage asserts and moves on; here it stops and offers a reason — a simile.

Blown a thousand times, no dross remains.

Sahasradha Dhmata Suvarnavat: Gold Smelted a Thousand Times

The reason is four words of prose — sahasradhā dhmāta suvarṇavat, "like gold blown a thousand times" — followed by two verses this edition numbers 104 and 105:

Dhmāta and dhmāne come from the root meaning to blow, referring to the bellows of a smelting furnace; kāñcana is gold. The image is metallurgical and would have been entirely familiar: a goldsmith removing impurity by repeated heating, and the observed fact that after enough passes the metal stops giving up dross, because there is none left to give.

Note the wording of the first verse, because it does real work: the malas are born in the six, ṣaṭsu dhātuṣu. Six, not seven. The text is not saying shukra is a dhatu of a different kind; it is saying that of seven dhatus, six sit in the chain such that something still comes off them, and one is at the end.

Two Similes, Opposite Jobs: Sugarcane Scum and Refined Gold

This next observation only appears when you set these pages against the ones before them.

The earlier part of the Dhatu Prakarana explains why every round throws off a mala, using a simile from the kitchen: ikshu-rasa, sugarcane juice, which throws up a scum each time it is boiled down. Boil, skim, boil, skim. That is a simile about recurrence — the scum keeps coming, and its coming is the normal case.

These pages explain why one round throws off nothing, and reach for a completely different craft: the smelting furnace and gold that has stopped yielding dross. That is a simile about termination — the point at which the removing is finished.

Ojas: The Sneha-Bhaga From the Waste-Free Round

Having established that the shukra round leaves no residue, the passage performs its familiar split one last time. The essence divides into gross and subtle, and the subtle portion is named: tatra sūkṣmaḥ sneha-bhāgaḥ ojaḥ — "therein, the subtle unctuous portion is ojas."

This is the structural claim the rest of the ojas material depends on, and it is worth stating plainly because it is usually lost when ojas is discussed on its own. Ojas is not an eighth substance added to the seven. It is what comes off the far end of the only round in the chain that produces no waste. Its position in the sequence is the argument for its quality: everything else in the body arrives with something still to be removed; ojas arrives from the one step where there was nothing left to remove.

Somātmaka carries the most freight. Soma here is the cooling, watery, moon-associated principle, standing opposite agni. To call ojas somatmaka places it firmly on the cooling side of the fundamental pair — a slightly awkward thing to say about the end-product of six successive cookings, and, as we will see, Charaka's version handles that awkwardness differently.

The Ten Gunas of Ojas in the Bhavaprakasha

The next verse expands the description to ten qualities, and the Hindi commentary counts them out: ojo daśa-guṇaṃ smṛtam, "ojas is remembered as ten-qualitied."

Read down the right-hand column and a pattern appears that the text never states. Most of the ten are the exact opposites of the qualities classical Ayurveda assigns to vata — light, cold, dry, rough, mobile, subtle. Ojas is heavy where vata is light, unctuous where vata is dry, soft where vata is rough, stable where vata is mobile, dense where vata is thin.

Snigdha, shveta, sthira, sandra.

"Charake Tu": Eight Drops, Seated in the Hridaya

Now the passage does the thing that makes it genuinely unusual. Having given its own definition of ojas, the compiler prints a bracketed heading — [charake tu], "but in Charaka" — and gives a different one.

Three differences from the Bhavaprakasha's own account, all of them material.

It has a quantity. Ashta-bindu pramana, the measure of eight drops. The Bhavaprakasha's own verse said ojas is sarva-śarīra-stha, situated in the whole body — a statement about distribution that gives no quantity at all.

It has an address. Hṛdi tiṣṭhati, it abides in the heart. Not distributed; located. This is the account developed at length in Charaka Samhita, Sutrasthana, chapter 17, the Kiyantahshirasiya Adhyaya, covered in our article on Charaka's chapter 17, and returning in the closing chapter of the same Sutrasthana, discussed in our article on chapter 30 and the ten great vessels.

It has two natures instead of one. The Bhavaprakasha said somatmaka. Charaka's verse says agni-somātmakatvena dvirūpaṃ — of the nature of agni and soma, and therefore two-formed. The Hindi commentary glosses this with durangā, two-coloured, and explains that the yellowish tinge is what the double nature produces: pure soma would be white, and the trace of agni is what shades it.

"Vagbhatashcha": Heart-Seated and Yet Pervading

The compiler then prints a second bracketed heading — [vāgbhaṭaśca], "and Vagbhata" — and gives a third account, the one appearing in the Ashtanga Hridaya's Sutrasthana in its chapter on the doshas and dhatus:

The first line does what the other two accounts do not: it resolves the contradiction instead of choosing a side. Hṛdayastham api vyāpi — "though heart-seated, pervading." Charaka had located ojas in the heart; the Bhavaprakasha had distributed it through the whole body; Vagbhata says both, and marks the tension with api, "though." It is a deliberate reconciliation, and the concessive particle is there so you notice it is one.

Three Definitions on One Page, Left Unreconciled

Step back and look at what has happened on a single printed page. A sixteenth-century compiler has set out:

Three positions, one after another, on a page that had every opportunity to pick a winner. There is no arbitration — two bracketed attributions and a change of subject.

This is the most interesting thing about the passage, and it is exactly what gets edited out when a doctrine is summarised. The received modern presentation of ojas tends to run the three accounts together into one composite — eight drops in the heart, pervading the whole body, white, the essence of all seven tissues — as though they were a single description delivered in instalments. They are not. They are three descriptions that disagree about location, quantity, colour and elemental nature, and the compiler who assembled them knew it, which is precisely why he labelled the sources.

Ojas and Bala: An Imprecision the Compiler Defends

The passage then takes up a question the three definitions raise: is ojas the same thing as bala, strength?

It begins by defining bala, and the definition is not the expected one. Ceṣṭāsu pāṭavaṃ yat tu balaṃ tad abhidhīyate — "that which is skill in actions, that is called bala." Not mass, not force, not the capacity to lift. Pāṭava is deftness, adroitness, competence at doing. Bala here is closer to capability than to power.

It then reports Sushruta's position — from the Sushruta Samhita's Sutrasthana, in the chapter on the increase and decrease of the doshas, dhatus and malas: that the supreme tejas of the dhatus from rasa through to shukra is precisely ojas, and that this is bala. Same thing, two names. The commentary explains the reasoning:

And then comes the most quietly remarkable line on these eight pages. Having identified ojas with bala, the text explains why the identification is allowed: tat-kārya-kāraṇayor abhedopacārāt — "because of the figurative treatment of cause and effect as non-different." Ojas is the cause; bala is the effect. Strictly they are two. They are being spoken of as one by a recognised figure of speech, and the text names the figure.

Then it gives the reason for permitting it: abheda-kathanaṃ ca cikitsā-saukaryārtham — "and the statement of non-difference is for the convenience of treatment."

That is a compiler telling his reader three things in one clause: that a technical imprecision is present; that he knows it is one; and that he permits it for practical rather than theoretical reasons. The simile offered alongside is domestic and exact: kṣīre ghṛtam iva, "like ghee in milk." The ghee is in the milk; it is not the milk; and for most purposes there is no reason to insist on the difference.

Utsaha, Pratibha, Dhairya, Lavanya, Sukumarata

The last thing the passage says about ojas is a list, and it is a list unlike any other in the chapter. Every previous list has been physical — tissues, channels, secretions, qualities of substance. This one is not.

The verse is not saying drive and quickness of mind are separate from the body and merely correlated with it. It is saying they are among the body's own properties, produced by the same substance that produces the sheen of the skin. A tradition deriving enthusiasm, wit, steadiness, lustre and fineness of texture from one bodily substance never divided the person into a mind and a body. The list looks miscellaneous only if you arrive expecting that division.

Artava the Seventh, Shukra the Eighth: A Different Count for Women

The passage closes its account of the chain with a question of enumeration. Having said the sthula portion becomes shukra, it adds that in women the same portion becomes artava, the menstrual substance, and shukra as well.

That raises an obvious problem for the count. The dhatus are seven; if women have both, they appear to have eight. The text takes it head-on: strīṇāṃ saptamo dhātur ārtavaṃ śukram aṣṭamam — for women, artava is the seventh dhatu and shukra the eighth.

The justification is a neat parallel: āśayādhikavat, "as with the additional ashaya." Women are held in this system to have one ashaya, one receptacle, more than men — the garbhashaya. Since the anatomy already carries an extra container, the tissue-count carrying an extra entry is not an anomaly needing special pleading; it is the same asymmetry appearing in a second place.

The verse this edition numbers 115 then assigns the two functions: strīṇāṃ garbhopayogi syād ārtavaṃ sarva-sammatam | tāsām api bala-varṇaṃ śukraṃ puṣṭiṃ karoti hi — artava is what serves the purpose of the embryo, and this is universally agreed; and their shukra too produces bala, varna (complexion) and pushti.

These pages carry further embryological material — the formation of the embryo, the roles of the two parental contributions — which sits outside this article's subject and which we cover separately in the article on garbhotpatti and the Bhavaprakasha's account of conception.

One Month and Nine Dandas: The Arithmetic That Checks Out

The last clause of the passage is a summary, and it contains a number that has sat there unremarked for four hundred years:

A danda — the commentary uses the everyday word ghadi — is one sixtieth of a day, twenty-four minutes. So the claim is that the whole journey, from the rasa produced by a meal to the shukra at the far end, takes one month plus nine dandas: thirty days plus three hours and thirty-six minutes.

Now recall the per-round figure, stated and restated at every stage: each dhatu holds the material for pañcāhorātrāt sārdha-daṇḍam, five days and nights and a danda and a half. Put the two numbers together and they resolve exactly.

The two figures are separated by several pages and never presented as related. The per-round figure sits buried in the repeated formula; the total appears in a closing summary a reader is likely to skim. Nobody says "multiply the one by six and you get the other." But you do.

And six is the same number verse 104 gave when it said the malas are born ṣaṭsu dhātuṣu, in the six dhatus. Two independent parts of the chapter — a verse about waste and a summary about elapsed time — agree that the count of transformations is six, not seven.

Six is correct because seven dhatus are joined by six transformations. Rasa is not made from a preceding dhatu; it is the material that enters the chain. Rasa to rakta, rakta to mamsa, mamsa to meda, meda to asthi, asthi to majja, majja to shukra: six steps, six holding periods, six malas.

A danda: one sixtieth of a day.

Reading the Mala Chain with Modern Eyes

It is easy to be unfair to this passage in either direction.

The physiology is not modern physiology and does not map onto it. Sweat is not a by-product of adipose tissue. Ear-wax is not produced by muscle. Nails and hair are not derived from bone, though the intuition behind the grouping is understandable. Nobody should read these pages as a description of how the body actually works, and the text makes no claim to a kind of authority it could not have had.

What the passage is — and this is not a small thing — is a serious attempt at a systematic account, in which every observable secretion is assigned a source, a carrier, a route and an exit, and the assignments follow from a general principle rather than being listed one by one. The principle is that a process which refines something must leave something behind, and that what it leaves behind must go somewhere. That principle is sound; it is roughly where any account of metabolism has to start.

Three features stand out as unusually careful by the standards of the period:

1. It states an exception and defends it. The shukra round breaks the rule, and the text offers a mechanism — drawn from a craft its readers knew at first hand — rather than merely asserting the break.
2. It records a disagreement it could have hidden. The iti eke clause and the three unreconciled definitions of ojas are both places where the compiler preserved a dispute rather than presenting a united front.
3. Its numbers reconcile. The per-round timing, the stated total and the verse's count of six all agree, across pages that never cross-reference one another.

A Short Glossary of the Sanskrit in This Passage

What This Article Is Not

This is a reading of a sixteenth-century text. It is a piece of history and it is not medical advice.

Nothing here describes how the human body actually produces sweat, ear-wax, nails or tears, and nothing here should be used to interpret anything about your own body. The classical scheme of dhatus and malas is a historical model of physiology, not a diagnostic framework. If you have a question about your health, consult a qualified doctor.

The same applies to ojas. This article describes what three classical texts say about it and where they disagree. It does not claim ojas can be measured, increased, depleted or assessed, and makes no recommendation about doing so.

From the Ayurveda Hub Shelf

The bridge from this page to our shelf is narrower than it might look. The passage above turns on a single craft idea: that refining is subtraction. The goldsmith's furnace adds nothing to the gold — it takes away, pass after pass, until there is nothing left to take. That is a fact about how materials are prepared.

Every item below exists because something was separated out and left behind. That is the only connection being drawn. It is a point about manufacturing and nothing more.
