Two giant men in topknots face each other across a packed ring of sand. They bow. They throw salt. They crouch inside a circle drawn on the floor, slam together, and one heaves the other out over the rope. To a stadium in Tokyo this is the most Japanese thing imaginable — sumo, the national sport, old as the islands. Dukes drops a quiet bomb in the middle of a footnote-heavy chapter: the most Japanese thing imaginable came from China, and the ring, the bow, and the very name still carry the fingerprints of a Buddhist movement-practice that crossed the sea centuries ago.1 The wrestler forgot where he was born. The evidence, Dukes argues, is hiding in his vocabulary.
This page records Dukes's claim that sumo descends from a Chinese Buddhist grappling art, and it records the chain of word-evidence he builds to support it. He starts in a sutra. In the Saddharma Pundarika — the Lotus Sutra — men are described performing arts written in Chinese characters as Shang-Cha and Shang-Po, also Romanized Hsiang-Cha and Hsiang-Po.2 Hsiang, he says, was used in Chinese Buddhist literature to render the Sanskrit Laksana or Nimmita — "characteristic" or "distinctive sign."3 Hsiang-Po he glosses as "distinctive (or adhering) grasping," meaning grappling or wrestling. And Hsiang-Po, he states, "is pronounced in modern Japanese as sumo — a famous form of wrestling which many do not realize comes from China."4
He then points at what travelled with the word. Japanese sumo, he says, still preserves ancient Chinese practices and rituals identical to those of the nata — the older Buddhist kinetic practice — and its derivatives: the bout is held inside a circular area, and there is a ritual bowing ceremony common to both.5 So the argument has two legs. The name decodes to a Buddhist wrestling term, and the surviving ritual furniture — the circle, the bow — matches the Buddhist parent practice rather than anything indigenous to Japan.
Dukes's boldest move is a second etymology, and it is the one to watch most carefully. He claims the suffix po derives from an ancient Chinese character meaning "one in authority" or — the phrase he chooses — "one permitted to strike you." That character, he says, stems from the Sanskrit root for "father," pitra. From that same root, he continues, we get the Latin pater. And the Japanese character fu (father) is, on his account, a simplified form descending from the Chinese po.6
Lay the links out and the chain is long: Sanskrit pitra → Chinese po (authority / "permitted to strike you") → Latin pater and → Japanese fu. Each link is a separate claim, and a chain is only as strong as its weakest joint. The semantic gloss — "father" sliding to "one permitted to strike you" sliding to a wrestling suffix — is doing heavy lifting, and the leap from a Chinese character to the Latin pater crosses an enormous linguistic distance on a shared meaning rather than a demonstrated descent. This is the part of the page that has to wear a warning label. The chain is suggestive and it is also exactly the kind of pleasing cross-language echo that real historical linguistics treats with suspicion.
The claim feeds the book's spine. It is one more instance of Nata: Kinetic Practice and Movement Meditation surviving in fossil form inside a later art that no longer knows its parent — sumo standing to nata as a folk dance might stand to a forgotten ritual. It supports Chuan Fa Transmission Lineage by adding wrestling to the body of physical practices that rode Buddhism out of India and China into Japan. And it gives Bodhidharma: The Revisionist Biography a companion specimen: another "purely Japanese" institution that, on Dukes's reading, is an imported Buddhist body-method wearing local dress, just as Daruma the doll is an Indian monk wearing Japanese paint.
The strongest plank in Dukes's case is not the etymology — it is the ritual residue, and it deserves a close look. He notes two specific survivals: the bout held within a circular area, and a ritualistic bowing ceremony common to both sumo and the nata.5 Why does this matter more than the word-decoding? Because rituals are sticky in a way meanings are not. A word can drift, be folk-etymologized, be coincidentally similar across languages. But a circular fighting area is an arbitrary, specific, non-obvious choice. There is no functional reason wrestling must happen in a circle rather than a square or an open field. When two practices on opposite sides of a sea both insist on the circle and both frame the contest with formal bowing, shared inheritance becomes a far more economical explanation than independent invention. The circle in the Buddhist material is not random either — the vault's representational-art tradition put sacred images inside circular borders to signify the 360-degree, all-around field of the teaching. So the sumo ring may be a faded mandala. This is the case study's payoff: the etymology is the flashy evidence and the contested evidence; the ring and the bow are the quiet evidence and the better evidence. A reader should weight them in exactly the reverse of the order Dukes presents them.
You are at a friend's place, sumo on the television, and you say out loud — half showing off — "you know this is actually Chinese." Your friend asks how you know. You feel the pull to reach for the exciting bit: the name sumo decodes from a Buddhist wrestling term, the suffix even links to the word father and to Latin pater. You open your mouth and then you stop, because you have learned to feel the difference between evidence and a good story. So you trade down to the boring, stronger thing. "Watch the ring," you say. "It's a circle. There's no reason wrestling has to happen in a circle. And watch the bow before they fight." You point at the formal etiquette bracketing the violence. "Same circle, same bow, in the older Buddhist practice it came from." Your friend nods, because that's checkable and it doesn't require believing a single author's chain across four languages. You keep the etymology to yourself — not because it's wrong, but because you can't defend it, and you've learned that the claim you lead with should be the claim you can stand behind when someone pushes.
Evidence base: a single passage of Dukes's notes-rich chapter, resting on his reading of the Saddharma Pundarika characters Hsiang-Cha / Hsiang-Po and his own Notes 34e, 36b, 36c, and 38.26 No independent linguistic authority is cited for the etymology chain.
The page splits its confidence deliberately. The descent-of-sumo-from-a-Chinese-grappling-art claim, supported by the circle-and-bow ritual survivals, is [PLAUSIBLE — needs corroboration] — there is a real, recognized current of scholarship on Chinese roots of various Japanese martial forms, and the ritual evidence is the kind that travels. The specific etymology chain — po from pitra, cognate with Latin pater, ancestor of Japanese fu — is flagged [LOW CONFIDENCE — contested] and must stay flagged. It is a folk-etymology-shaped claim from a single practitioner-scholar with no comparative-linguistics citation, and the vault preserves it as something Dukes argues, not as fact.
Open: Dukes says "the Sanskrit terms for what Hsiang Cha implies here mean something else again, but more of that elsewhere"7 — he defers the Hsiang-Cha decoding. The full Laksana / Nimmita reading is left dangling in this passage, an unclosed seam in his own argument.
Dukes is a practitioner-scholar decoding his own tradition's vocabulary, and that is both his power and his exposure here. The power: an insider who has trained the body-methods can recognize a fossil practice — the circle, the bow — that an outside philologist scanning texts might never connect to a living mat. The exposure: an insider also has every incentive to find his tradition everywhere, and etymology is the easiest place in the world to find what you're looking for. The po → pater chain is exactly where enthusiasm outruns method. A comparative linguist would want a regular sound-correspondence, attested intermediate forms, and a reason to think two language families are even related before accepting that po and pater share an ancestor; Dukes offers a shared meaning and a confident sentence. The vault holds the tension without resolving it: the man who can see the surviving ritual because he practices it is the same man who will hear father in a wrestling suffix because he wants the lineage to be unbroken. Both things are true at once, and the page keeps them both.
Nata: Kinetic Practice and Movement Meditation — the nata page describes a Buddhist kinetic practice that decayed into static, half-understood remnants once its parent tradition lapsed, surviving mostly as frozen postures in mandalas. Sumo is the same decay running the other direction — outward into a secular national sport instead of inward into a devotional image. Put the two cases beside each other and an insight appears that neither gives alone: a body-practice can outlive its meaning in two opposite ways, fossilizing as sacred art or as popular contest, and in both cases the practitioners keep performing the form while losing the why. The circle and the bow survive in sumo as etiquette nobody can explain; in the mandala they survive as iconography nobody re-derives. The vault gets a general claim about cultural transmission: ritual form is more durable than ritual meaning, which is exactly why a forgotten origin can be recovered from the form long after the meaning is gone.
Bodhidharma: The Revisionist Biography — that page argues Bodhidharma was a man inflated into a legend, an obvious Indian remembered as "quintessentially Chinese." Sumo is the inverse operation on a practice rather than a person: a Chinese import deflated into a purely Japanese self-image, its foreign origin forgotten rather than its human origin exaggerated. Set the two together and you see one mechanism with two outputs — a culture rewrites the provenance of what it has absorbed, sometimes by claiming a foreigner as its own, sometimes by claiming an import as native-born. The shared insight: national origin stories are negative evidence. The harder a culture insists something is purely its own, the more worth checking whether it walked in from somewhere else — and the etiquette around the thing, the circle and the bow, is where the customs stamp survives.
Sharpest implication: if ritual form outlasts ritual meaning, then the way to trace a "native" practice back to its real origin is to ignore what people say it means and study the arbitrary, functionless conventions they can't explain — the circle, the bow, the salt — because those are the parts too pointless to have been reinvented.
