A man pours new wine into a barrel and you can taste the old barrel in it. The wine is his, but the wood gave it a flavor that was already there before he poured. Dukes, in a single footnote, holds up the foundational commentary on the Yoga Sutra and says he can taste the barrel. The commentator Vyasa, writing his summary of the yoga system, reaches for words the Vedas never had — Samsara, Moksa, Hetu — and lays out his whole medical scheme in a shape that belongs to someone else: disease, its cause, health, its cure. That is the Four Noble Truths with the labels filed off. Dukes reads this as a fingerprint. The yoga system, he argues, was poured into a vessel Buddhism had already built.1
This page records a single, sharply stated claim from Dukes's notes: that Hatha Yoga as a systematized practice developed after Buddhism and borrowed from it, rather than handing Buddhism a pre-existing technology of the body.2 He gives two kinds of evidence. The first is lexical. Vyasa, the commentator who fixed the meaning of the Yoga Sutra for centuries, uses several technical terms that, on Dukes's account, were "previously unknown in the Vedas" — Samsara (the round of rebirth), Moksa (release), Hetu (cause). If the words show up first in Buddhist literature and only later in the yoga commentary, the direction of the loan is fixed by the calendar.3
The second is structural. Vyasa frames his account of the medical art — disease, its causes; health, and its cures — on the format of the Four Noble Truths: suffering, the origin of suffering, the cessation of suffering, the path.4 Dukes generalizes the move: "As the Yoga system developed, it borrowed many Buddhist ideas and re-interpreted them to suit its own usages and doctrines."5 And he adds a detail that stings more than the dating: in the early texts, the word Yoga itself is used pejoratively — a slur, not a badge — in both the Theravada Pali Mahavastu and the Mahayana Sanskrit Prajnaparamita literature.6 The thing that would later name a global wellness industry started life as an insult in the very tradition Dukes says it borrowed from.
Run the logic the way a forensic accountant runs a set of books. You are not looking for a confession; you are looking for items that could only have come from one source. A vocabulary word is one such item. If Vyasa needed Samsara to say what he wanted to say, and the word was not in his own scriptural inheritance, then he reached over the fence for it. One borrowed word is an anecdote. Three — Samsara, Moksa, Hetu, all load-bearing, all naming the architecture of liberation itself — start to look like a pattern.
The format argument is stronger still, because format is harder to borrow by accident than vocabulary. Anyone can pick up a foreign word. To structure your entire medical theory on someone else's four-part diagnostic frame, you have to have studied that frame closely enough to internalize its shape. The Four Noble Truths are not just four claims; they are a clinical sequence — name the symptom, find the cause, assert the cure exists, prescribe the treatment. When Vyasa's medicine marches in that exact order, Dukes reads it as a man who learned to think in a borrowed grammar and then wrote in it without translating. The pejorative use of "Yoga" closes the loop: a tradition does not insult a word it reveres. The slur marks the period before the borrowing was complete, when "yoga" still named something the Buddhist authors looked down on.
This page hands the rest of the vault a dating spike — a single hard claim that can be driven into the soft ground of any "yoga is the oldest" assumption. Vajramukti as Buddhist Martial Philosophy depends on the Buddhist body-method being the origin rather than a late adopter of pre-existing yoga; Dukes's footnote is the buttress under that claim. Theravada vs Mahayana Structural Organization supplies the two literatures (Pali and Sanskrit) where the pejorative "Yoga" surfaces, so the slur can be located on both sides of the Buddhist split. And for any future page on the Yoga Sutra's eight limbs, this note flags that the systematizer's own vocabulary betrays a later, Buddhist-soaked composition. The gift to the vault is not a settled fact — it is a sharp, citable, contested claim that forces every antiquity argument to show its evidence.
Take Dukes's own example apart. He names Vyasa as "the commentator of the Yoga Sutra" and lists the three terms — Samsara, Moksa, Hetu — as "unique Buddhist terms previously unknown in the Vedas."3 Read that phrase carefully and you see the whole argument hinge on one empirical claim: that these words are absent from Vedic literature and present in Buddhist literature first. Dukes does not prove the absence in the footnote; he asserts it. That is the soft joint. If a scholar of Vedic Sanskrit could show Samsara or Hetu in pre-Buddhist usage, the lexical leg of the argument wobbles.
The format leg is sturdier and Dukes leans on it harder. His sentence is precise: Vyasa "bases his summary of the medical art as disease, its causes; health, and its cures, upon the format of the Four Noble Truths."4 Notice he claims the format, not the content. He is not saying yoga stole Buddhist medicine; he is saying it stole the shape of Buddhist diagnosis and poured its own medicine into it. This is the more sophisticated charge, because it survives even if the medical details are entirely Indian. A borrowed container with native contents is still a borrowed container. The case study, in miniature, shows Dukes doing exactly what he does to Bodhidharma's legend elsewhere: reading a structure as a fingerprint, and trusting form over vocabulary because form is harder to fake.
You are a fact-checker with the Yoga Sutra commentary open on one screen and a concordance of Buddhist Pali terms on the other. Someone has handed you a draft that opens "Yoga, the most ancient of India's spiritual sciences, predates the Buddha by millennia." Your job is to test the sentence, not to like it. You start with the word "ancient." You find Vyasa — the man who fixed what the Sutra means — reaching for Samsara. You search the Vedic corpus for it and the hits are thin and late. You note that. Then you check the medical passage and lay it beside the Four Noble Truths, line for line: symptom, cause, cure-exists, path. They rhyme. You feel the draft's sentence start to invert under your hands — not "yoga predates the Buddha" but "yoga's foundational commentary thinks in the Buddha's categories." Then you stop yourself, because you are a careful reader and you know Dukes is a partisan. You write in the margin: check whether these words are really Vedic-absent; one independent Sanskritist could collapse this. You leave the claim standing but flagged — sharp on one end, soft on the other — which is exactly how it came to you.
The evidence is one densely packed footnote (Dukes's Note 8b), which cites the Pali Mahavastu 3:384-10 and the Sanskrit Prajnaparamita (Ghosa's Calcutta edition) for the pejorative use, and asserts the Vyasa borrowings on Dukes's own authority.7 [CONTESTED] governs the entire page. This claim runs directly and deliberately against the vault's critical-historical corpus.
The tension is the richest cross-source collision in the Bodhisattva Warriors ingest, and it must be preserved, never resolved. Dukes says Hatha Yoga postdates and borrows from Buddhism. The vault's Samuel material dates the subtle-body and systematized yoga to a long, layered development with its own pre-Buddhist substrate, and the WarYoga corpus (Billinge, Zurxane, Palaistra) argues for an even older martial-ascetic lineage feeding into modern yoga from the akhara, not from Buddhist Chuan Fa. White's critical-historical work treats yoga's "antiquity" claims with suspicion but does not hand the origin to Buddhism. So three positions sit in the vault unreconciled: Dukes (Buddhism is the donor), Samuel/White (a layered Indian development, antiquity over-claimed), and WarYoga (a martial-ascetic akhara lineage older than the textual record). Each has a different motive and a different warrant. Hold all three open.
Open question: are Samsara, Moksa, and Hetu genuinely absent from pre-Buddhist Vedic and Upanishadic Sanskrit? A single competent Sanskritist could confirm or collapse Dukes's lexical leg, and the whole borrowing thesis rests heavier on that than Dukes admits.
Dukes is not a neutral observer here and the page should say so out loud. He is a Buddhist Chuan Fa lineage-holder whose entire book argues that the Buddhist body-method is the fountainhead of the East Asian martial and yogic traditions. A footnote claiming yoga borrowed from Buddhism is exactly the conclusion his project needs — which does not make it wrong, but does make it interested. Set him beside Geoffrey Samuel and the contrast is instructive. Samuel demythologizes yoga's antiquity from outside any lineage, in the open academy, with checkable citations, and his conclusions stay deliberately thin: we cannot know how old the subtle body is. Dukes demythologizes yoga's antiquity from inside a rival lineage, and his conclusion is thick and pointed: it borrowed, and from us. Reading them together, you watch two men attack the same myth — "yoga is timeless" — from opposite banks, and you notice that Dukes's attack quietly installs a replacement origin (Buddhism) where Samuel installs only a question mark. Where Dukes converges with the whole critical corpus: nobody serious in this vault takes yoga's self-described antiquity at face value. The fight is only over what stands in its place.
Bodhidharma: The Revisionist Biography — these two pages run the same engine in opposite gears, and seeing them together exposes Dukes's method as a method. On the Bodhidharma page he argues against the deflators: the man is real, the legend is compressed information, don't dissolve him. Here he is the deflator: yoga is not as old as it says, it borrowed, read the fingerprints. Same reader, same forensic toolkit — date the sources, watch the vocabulary, trust structure over self-description — pointed once to inflate and once to deflate. The insight neither page produces alone: Dukes's source-criticism is not a neutral instrument but a lineage-defending one. It dissolves rivals' antiquity claims and firms up his own tradition's founder. A vault that holds both pages learns to ask of any demythologizer: which myth survives your method, and does it happen to be yours? That question is the real takeaway, and it generalizes far past Dukes.
Samuel's Critical Anthropological Method — Samuel and Dukes agree on the negative and split on the positive, and the split is the whole lesson. Both refuse "yoga is immemorial." But Samuel's refusal terminates in agnosticism backed by open citations anyone can audit; Dukes's terminates in a counter-claim (Buddhist priority) backed partly by his own temple's manuscripts and his own assertion of Vedic absence. The structural parallel: each man uses dating-against-the-sources to unseat a tradition's self-image. The tension: an outsider's deflation leaves a gap, an insider's deflation fills it with his own tradition. Put together they generate a working rule the vault needs whenever it meets an antiquity dispute — separate the deflationary claim (this is younger than it says) from the substitution claim (and here is the real source). The first can be true while the second is special pleading. Dukes's footnote is strong on the first and motivated on the second, and only by reading him through Samuel does that seam become visible.
Sharpest implication: if a tradition's foundational commentary thinks in a rival's vocabulary and diagnostic format, the borrowing may run so deep that the tradition cannot see its own debt — the most "native" categories are the imported ones.
