A monk stands in an empty hall and is told: a man you have wronged arrives at the gate, grieving and armed. Show us. There is no opponent, no script of lines — only the set situation and the body that must enact it, fully, as if it were real. He is not performing for an audience. He is being walked through a charged encounter on purpose, so that whatever lives in him under pressure has to come out where it can be seen and worked with. Kempo gave this practice a name centuries before Western psychology arrived at the same idea and called it psychodrama.1
Kagejitsu is the Kempo tradition's "unique practice of dramatic mime," in which participants have to enact certain set situations.2 Dukes places it inside a larger distinction between two modes of Buddhist expression. "Selfless" expression is accomplished mainly by working for others without reward — but it can also name situational encounters within which only a selfless response is adequate.3 "Self" expression names the fulfillment of duties and responsibilities toward others, as in teaching or healing body and mind.4 Kagejitsu sits on the "self" side: it is the deliberate, willed enactment of a charged situation so that the practitioner's response can become visible.
Two things matter in how Dukes frames it. First, the dating claim — "These methods are very old and predate certain very modern forms of psychology which are now beginning to use similar methods called 'psychodrama.'"5 Second, the company it keeps: the very same note explains why sparring itself was introduced. Selfless situational encounters "occurred in both Chaan Buddhist encounters and in the application of Kempo. These were the main reasons for the introduction of sparring practices between fellow students."6 So the set-situation enactment and the live sparring partner are two answers to one question: how do you create a situation that only a selfless response can solve?
Think of a flight simulator. The pilot is not really in a storm, yet the body does not fully know that — heart rate climbs, hands sweat, the wrong reflex shows itself in safe conditions where it can be corrected. Kagejitsu is a simulator for the inner life. The set situation is the weather: chosen, controlled, and charged enough that the practitioner's real responses surface rather than hide.
The leverage is in the word enact. The monk does not discuss how he would respond to the grieving armed man; he embodies it. And embodiment recruits the whole person — posture, breath, the catch in the throat — in a way that talking about it never can. Whatever defense, fear, or self-assertion lives below the level of report gets pulled into motion, where the body can no longer keep it offstage. This is why the practice belongs to the "self" expression category and not to abstract contemplation. It is expression — the inner content forced outward into form, so it can be met.
And because the situation is set by a teacher, it is curated. The encounter is built to require a selfless response, the way the koan is built to defeat reasoning. The student cannot route around the demand. The enactment puts them inside a moment where the habitual, self-protecting reflex is exactly the wrong move, and the only adequate move is the one that lets the self drop. That is the rationale Dukes gives for sparring, applied here to mimed scenario rather than live contact.6
This page gives the vault its bridge between contemplative encounter and physical sparring. Situational-Encounter Sparring as Revelation treats sparring as a revealer of the practitioner's state; kagejitsu is the same revealer working through enacted scenario instead of a live partner, and Dukes roots both in the identical "selfless situational encounter" logic. Samasthana Tests and the Unborn Mind describes engineered situations that outrun the ordinary mind; kagejitsu is the lower-intensity, dramatic cousin — engineered situation as theatre rather than combat. Kata as Inward Training gets its experiential frame here: the kata is itself a self-revealing internal environment, and kagejitsu names the wider family of enacted forms that work that way.
Dukes's note 58 is unusually dense — three practices stacked in a few sentences, and reading them together shows they share one root.7 The note opens by defining selfless expression, then immediately gives the situational reading: encounters within which only a selfless response is adequate, in both Chaan and Kempo, "the main reasons for the introduction of sparring practices."6 Then it pivots to self-expression, and lands kagejitsu there: dramatic mime, enacting set situations, predating psychodrama.5 Then, in the very next note-section, the kata: the formal movement sequences of Kempo, "another method oriented toward self-revealing (Sanskrit: Pratyanubhavati) internal environments."8
So three things — sparring, kagejitsu, kata — appear in a single breath, and the connective tissue is self-revealing internal environments. Sparring reveals through a live opponent. Kagejitsu reveals through enacted scenario. Kata reveals through prescribed solo form. The Sanskrit Dukes attaches to the kata, pratyanubhavati, "self-revealing," is the load-bearing term for the whole cluster: each practice is an environment built so that the practitioner's interior is shown back to them. The case study is the note itself — Dukes has filed three apparently different drills under one psychological function, and the filing is the insight. Sparring is not primarily about winning, kagejitsu not primarily about acting, kata not primarily about technique. All three are mirrors in motion.
The hall is dim, the floor swept. The senior names your scene: the one you failed to protect stands before you, and asks why. No partner steps forward — you face empty air. You begin. Your shoulders come up before you decide to raise them; that is the old armor, arriving uninvited, and the watching teacher sees it the moment you do not. You reach toward the imagined figure and your hand stops short — a flinch, a self-protection, surfacing in the gesture. You feel the pull to make the scene about your own remorse, to perform sorrow that centers you. The teacher's stillness tells you that is the self-expression curdling into self-display. You let the centering thought go and reach again, this time toward the figure rather than around your own guilt. The gesture completes. Something in the chest unlocks. The empty air held nothing, and it showed you everything.
The source is Dukes's note 58 in full, with the kata material in the adjacent note-section.1 The whole entry is compressed practitioner exposition — three practices defined in a handful of sentences — so each definition is a paraphrase of a paraphrase, and the categories ("selfless" vs "self" expression) are Dukes's own organizing scheme rather than quoted doctrine.
The load-bearing tension is the dating claim. Dukes states flatly that kagejitsu "predate[s] certain very modern forms of psychology... called 'psychodrama.'"5 Psychodrama as a named method is J. L. Moreno's, early twentieth century — that part is uncontested. But the claim that a specific named Kempo mime practice is "very old" rests on Dukes's lineage authority, not on cited external attestation, and the temple-manuscript provenance of much of his Kempo material means this is exactly the kind of claim a critical historian would want a primary source for. [PLAUSIBLE — needs corroboration]
Open: is kagejitsu attested in any Kempo or Chaan text outside Dukes's lineage sources, and under this name? And did the practice carry an explicitly therapeutic intent, or is the resemblance to psychodrama a convergence of form without shared aim — selfless-response cultivation arriving at the same method psychodrama reached for catharsis?
Dukes makes a dating-and-priority claim — old Kempo mime predates modern psychodrama — and stakes it on his practitioner's authority rather than on external citation. Hold it as his conviction, not as established chronology: the existence and antiquity of a named kagejitsu practice is precisely the sort of lineage claim his privately-held temple sources underwrite and outside scholarship has not independently confirmed. Where he converges with the broader vault and with his own book's spine: the refusal to treat any of these drills as merely technical. Sparring, mime, and kata are all "self-revealing internal environments," and that functional unity is consistent with his consciousness-appendix insistence that the whole martial apparatus is a consciousness-practice in disguise. The convergence is strong even where the historical-priority claim is thin — one can grant that kagejitsu functions like psychodrama while withholding judgment on which came first.
Psychodrama and Role Enactment — Moreno's psychodrama puts a client inside an enacted scene so that material inaccessible to talk becomes available through embodiment; the body says what the mouth cannot. Kagejitsu uses the identical engine for a different destination. Where psychodrama aims at catharsis, integration, and symptom relief, kagejitsu aims at the selfless response — the dropping of the self-protective reflex that a charged encounter demands. The insight neither tradition reaches alone: psychology supplies the rich modern account of why enactment surfaces hidden material — embodied cognition, state-dependent access, the recruitment of motor and affective systems that verbal report bypasses — and the Kempo frame supplies a target the therapeutic frame rarely names, namely that the point of surfacing the material is not to discharge it but to let the self thin in real time. Run psychodrama with the selfless-response aim and you get a contemplative technology; run kagejitsu with a therapeutic aim and you get something close to Moreno. Same mirror, two faces looking in.
Kata as Inward Training — Kata and kagejitsu are the solo and scenario forms of one practice: the self-revealing internal environment. Kata reveals through fixed, repeatable sequence — the same form done until what you bring to it shows up against the constant. Kagejitsu reveals through varied, charged scenario — the situation changes so that what you bring to novelty under pressure shows up. Put the pair together and you get a complete revealing apparatus: the constant form exposes your standing habits, the variable scenario exposes your reactive ones. Neither domain alone gives you the pair. The martial literature treats kata as technique-storage and kagejitsu, where it survives at all, as quaint role-play; reading both through pratyanubhavati reveals them as instruments of the same self-disclosure, which is the thing the technique-storage reading entirely misses.
Sharpest implication: to see what you actually are under pressure, you do not need a real crisis — a set and enacted one, fully entered, will show you the same thing, which is why the temple built theatres of the inner life.
