The Rasārṇava says something that should stop a Hindu reader cold: "He who eats cow meat and drinks the liquor of immortality, him I consider to be one of the kula and a knower of mercury."1
Cow meat. To most Hindus then and now, eating beef is close to the worst thing a person can do. And drinking liquor isn't far behind. So is this book really telling its holy practitioners to commit two of the gravest taboos at once?
No. It's using a code. "Eating cow meat" (gomāṃsa) and "drinking the liquor of immortality" (amaravāruṇi) are stock phrases of a secret yogic vocabulary. They don't mean what they say. According to a commentator explaining the identical phrases in a later yoga manual, they refer to a single advanced practice: khecarī mudrā, in which the yogin curls his tongue back and up, and internally swallows his own bodily essence after it has been transmuted into nectar.2 No cow dies. No alcohol is poured. The words are a shell, and the kernel inside is a yoga technique.
This is the famous "twilight language" of Tantra — sandhā-bhāṣā, talk that sits in the dusk between literal and figurative. The tradition is full of it: instructions that sound like recipes for transgression but encode inner practices.
Here's the move. The text names a forbidden substance — beef, liquor, the "five nectars" of bodily fluids. On the surface, it reads as a license to break taboos. But the initiated reader knows the phrase points elsewhere: to a breath technique, a tongue position, an inner absorption of one's own refined essence.3 The shock value is deliberate. The transgressive surface keeps the outsider away and marks the insider, who knows the phrase is a key, not a command.
For the Rasārṇava specifically, this code resolves what looks like a flat contradiction in the book. Chapter one mocks the Tantrics who think eating meat and handling fluids will save them.4 Then it praises the man who "eats cow meat and drinks the liquor of immortality."1 Same book, opposite signals — until you realize the first is literal (don't actually wallow in flesh and liquor) and the second is coded (do practice the inner tongue-and-nectar yoga). The author isn't confused. He's drawing a line between the crude literalists and the refined adepts who understand that the "meat" and "liquor" were always pointing inward.5
The code language isn't just secrecy for its own sake. It marks the seam where alchemy meets yoga.
Indian alchemy ran on what White calls "the Work in Two Parts."6 Part one is the laboratory work — purifying mercury, fixing it, combining it with minerals. Part two is the bodily work — the yoga that does to your own fluids what the lab does to the metal. The two halves mirror each other, and the practitioner ran both.
The coded phrases live exactly at that seam. When the Rasārṇava tells the alchemist to "eat cow meat and drink the liquor of immortality," it's pointing him from the pot to his own body — telling him to do the hathayogic complement to his chemical work, to internally absorb his transmuted essence the way he fixes mercury in the pot.2 The code is how the text reminds you that the outer chemistry and the inner yoga are one job. You'd miss that entirely if you read the phrase as a dinner order.
This page is a small but essential decoder. It tells the rest of the alchemy material how to handle the tradition's most shocking lines: don't take them flat.
It directly serves the Rasārṇava by resolving its apparent self-contradiction. It connects to the master thesis that the human body is an alchemical body — because the code is precisely the hinge where lab-language gets re-applied to the body. And it ties to vajrolī mudrā, another practice of catching and reabsorbing one's own fluid rather than spending it — the same logic of keep it, don't lose it that the "liquor of immortality" encodes.
There's a second reading of these phrases, and it's worth taking seriously precisely because it's so concrete.
A Tribhuvan University professor, Mukunda Raj Aryal, gave White a different interpretation, drawn from watching real temple-roof gilders at work in the Kathmandu Valley.7 To gild a roof, the workers use a mercury-gold amalgam. Mercury vapor is poisonous. And Aryal noticed that while the gilders handled the amalgam, they stuffed their mouths with chunks of raw meat and regularly rinsed their mouths with alcohol.
Why? Almost certainly as crude protection — the meat and the alcohol were practical attempts to keep from inhaling or swallowing the mercury fumes.7 On this reading, "eat cow meat and drink the liquor of immortality" might not be twilight language at all. It might be a literal, sensible workshop instruction: when you're working with toxic mercury, keep meat in your mouth and alcohol on hand.
White doesn't choose between the two readings, and that's the honest move. The phrase might be coded yoga, or it might be practical mercury-safety, or — most likely — it might have lived as both at once: a real workshop habit that hardened into a mystical code, its toxic-practical origin forgotten as the yogis spiritualized it. The double reading is a small lesson in how easily a concrete craft-practice can curdle into secret doctrine.
White gives the scholar's decode of one coded pair. A practitioner, Selvalingam, gives a different one — for the famous five M's (the pañca-makāra), and from inside a living lineage rather than a manuscript.8 It doesn't replace the gomāṁsa-equals-khecarī reading above; it sits beside it as a second gloss, and the two don't have to agree, because twilight language was never one fixed cipher.
Here is his key. Māṁsa — meat — decodes to mauna, silence: you "eat the tongue," meaning you still it, you stop speaking and turn the organ of speech inward.8 Matsya — fish — is the holding of the breath, the slippery thing caught and stopped.8 Mudrā — usually parched grain — becomes keeping the body itself still, frozen in posture.8 And maithuna — sexual union, the most scandalous of the five — decodes to the kuṇḍalinī-śakti arriving in the cakra, the inner union of the risen energy with its seat, no partner required.8 Four taboos, four inner stillnesses-and-arrivals.
Then the twist that makes the code a code. Selvalingam says the texts lie on purpose.8 They give a deliberately wrong list — an outer set of substances to mislead the uninitiated, while the inner set is the real referent. The obfuscation isn't a byproduct of secrecy; it's engineered. The wrong list is the lock, the right list is the key, and the text hands you the lock in plain sight precisely so the key stays hidden. That is the same in-group filter the page already names, now confirmed from the practitioner's side: the misdirection is intentional, and reading the surface list as instruction is exactly the mistake the surface list was built to produce.
You hit a line in a Tantric or alchemical text that tells you to do something forbidden — eat the unclean thing, drink the intoxicant, break the taboo. Before you react, run it through two readings.
First, ask: is this a known code phrase? The big ones — beef, liquor, the five nectars, the five M's — almost always double as twilight language for inner practices. If the text elsewhere mocks people who take such things literally, that's your tell that the shocking line is coded.4 Read it as a tongue-position, a breath, an inner absorption, and see if it suddenly fits the surrounding instructions.
Then, second, ask Aryal's question: could there also be a literal, practical origin? Don't assume "symbolic" is the whole answer. The meat-in-the-mouth might really have started as mercury safety. Hold both. The richest reading of these phrases is usually the one that refuses to pick — that sees a concrete practice and a coded meaning braided together, with the concrete one older than anyone now remembers.
There are two ways to get this wrong, and they're mirror images.
The first is to read everything literally. This reader sees "eat cow meat" and concludes the Tantrics were beef-eating taboo-breakers, full stop. They miss that the phrase is a key and march off with a caricature of the tradition as pure transgression.
The second is to over-spiritualize. This reader knows about twilight language and so dissolves every shocking instruction into pure symbol — there's no real meat anywhere, it's all inner yoga, the bodies and substances were never material. That reader would wave away Aryal's gilders entirely, and would miss that the codes often grew out of genuinely physical practices. White's whole project resists exactly this flattening: the tradition is real mercury and real yoga, literal and coded, and the codes frequently have toxic, concrete roots. Collapse it to "just symbolic" and you lose the cauldron; collapse it to "just literal" and you lose the body. The truth is the braid.
The coded reading rests on a commentator (Brahmānanda) glossing the identical phrases in the later Haṭha Yoga Pradīpikā as khecarī mudrā, which White applies back to the Rasārṇava.2 The literal-practical reading rests on Aryal's firsthand observation of Kathmandu gilders.7
The live tension is that White presents both and resolves neither. That's the open question this page holds: when a code phrase has both a mystical meaning and a plausible practical origin, which came first — did a craft-safety habit get spiritualized into doctrine, or did a doctrine get rationalized into a craft-habit? The gilders suggest the former, but the evidence doesn't force it.
There's really one source here — White — but he stages a tension within his own account by refusing to collapse the two readings. The commentator's gloss says the phrase is pure inner yoga. Aryal's observation says it might be pure mercury safety. White lets both stand.
What that refusal reveals is a methodological stance worth naming. White trusts that a single phrase can carry a concrete origin and a mystical meaning at the same time, and that forcing a choice between them would falsify the tradition. The convergence the reader should take away isn't between two authors but between two truths about the phrase: that the most honest reading of a coded line often keeps the body and the symbol in the same frame, because that's how the tradition itself held them.
Plain version: insider codes work by saying something shocking on the surface so that only those who hold the key understand the real, harmless meaning underneath — and those codes often start as concrete practices that later get mystified. That pattern shows up in how groups signal membership and in how language drifts.
The sharpest version. A taboo-breaking instruction is often the safest thing in the text, because it's not an instruction at all — it's a password. The shock is the lock; the coded meaning is the key; and the people most scandalized are exactly the outsiders the code is built to keep out. This should make you suspicious of your own scandalized reactions to any closed tradition's "shocking" doctrines: the offense you feel might be the precise effect the code was designed to produce in someone who doesn't hold the key.
