A pilot does all his hard thinking on the ground. He runs the pre-flight checklist, walks the failure cases, pictures the engine cutting out on takeoff and his hands already moving to fix it. He does this so that once the wheels leave the runway, he never has to stop and think — his hands just go. The thinking happened on the ground precisely so the body could act in the air.
Keikaku — planning — is the warrior's version of that checklist. Lovret says combat is mostly instinct, and the man who thinks during it dies.1 But there is one narrow window where the mind belongs: before. Before contact, you study the enemy and the ground, and you pre-load a handful of moves. Then you shut the mind off and let the body run them.
Keikaku is the planning phase of a fight, and it has a hard boundary: it ends the instant the fight starts.
Lovret's earlier rule was blunt — thinking during combat gets you killed, because the half-second you spend deciding is the half-second the other man uses to hit you.1 Keikaku doesn't soften that rule. It carves out the one place where thought is allowed and useful, which is the time before blades touch. The key word, he says, is before.1
Here is what you do in that window. You make a careful study of the enemy and the terrain. From that study you pick several strategies — a variety of heihō, different styles — that might fit the coming fight. You deliberately do not lock onto one, because a battle almost never goes to plan.1 You stock the shelf with options so that when the situation suddenly demands one, your body reaches for it without you choosing.
Then comes the in-yō payoff. As contact nears, you stop seeing yourself, the enemy, and the ground as three separate things. You treat them as one event. When you can hold that — no separate "you" standing apart, afraid — the fight stops being a thing to dread. Lovret's line: how can you be afraid when there is no you there?1
The logic runs on a single split in time. Up to the moment of contact, the mind is the right tool. After contact, the mind is a liability. So everything mental has to get done early.
That is why you pre-select a variety and never fix on one plan. Fixing on one plan means that when the fight veers — and it will — you have to stop and re-decide in the worst possible moment. A shelf of options means the body grabs the one that fits and runs it instantly, no deciding required.1
The strange part is the review itself. Lovret says when you quietly run these strategies through your mind beforehand — not intending to use them, just looking at them — your body instinctively flexes the matching muscles. The mental rehearsal physically primes you. The gain may be small, but small is sometimes the whole margin between winning and losing.1 You are not just memorizing a plan. You are warming the exact muscles that plan needs, by picturing it.
This is why the boundary holds and doesn't contradict "the man who thinks dies." The thinking already happened. By the time contact lands, the deciding is over, the muscles are primed, and the "you" that could hesitate has dissolved into the single event of the fight.
Keikaku leans directly on the in-yō doctrine of non-duality. The planning window ends in the act of collapsing self, enemy, and ground into one event — which is what In-yō as Japanese Grammar describes as the basic grammar under which all of Lovret's combat thinking is conjugated. Keikaku is where you load that grammar before you have to speak it under pressure.
It also hands off cleanly to mushin. The point of doing all the thinking before is to enter contact empty — no deliberation, no commentary. Mushin, the No-Mind State is the destination; keikaku is the on-ramp. You think hard now so you can have no mind later.
And it sits on top of the technique/strategy split. The variety you pre-select is a variety of strategies, not raw techniques — see Technique vs. Strategy Distinction. Planning operates at the strategy layer; the body supplies the technique on the fly.
Take Lovret's own claim and watch it work. You are studying a coming fight. You pick three strategies that might fit. You sit and quietly run each one through your mind — not to commit, just to look.
According to Lovret, as you do this your body flexes the muscles each strategy would use.1 So picturing a low entry tightens the legs; picturing a sword bind warms the forearms and grip. You have not moved. But the muscle has already been told what might be coming. When the moment arrives and one of those three fits, the body is half-warm and the move comes faster than cold. That is the mechanism behind "the advantage may be small but may decide the fight."
Now layer the in-yō piece. As you finish reviewing, you choose the strategy that welds enemy, self, and ground into one entity.1 You picture the enemy's face stuck to your fist, his body wrapped around your blade, the ground as the soles of your feet. There is no longer a separate fighter to protect. And here is the worked payoff: with no separate "you" on the field, there is nothing left to be afraid for. Fear needs a self to defend. Dissolve the self into the single event and the fear has no object. The battle stops being dreaded and becomes something you eagerly await.1
You have an hour before it starts. You sit where you can see the ground — the room, the slope, the trees, whatever it is. You watch the other man move. You note how he carries his weight, which side he favors, where the terrain pinches.
You pick three moves. Not one — three, of different shapes, because you already know this won't go to plan. You don't pick them to use. You pick them to look at. You run the first through your mind, slow. You feel your thighs tighten as you picture the entry; you let them. You run the second; your grip warms. You run the third; your shoulders set. You don't move a muscle on purpose. The body does it on its own, and you let it.
Now you stop separating things. You look at the man and you stop seeing him over there and you over here. You picture his face already against your fist, the ground already under your feet like a second skin. The line between the three of you goes quiet. You feel the fear go looking for someone to protect and find no one home. The dread drains out. You catch yourself almost wanting it to start.
Then it starts — and you stop thinking entirely. The shelf is stocked. The body takes over.
There are two ways keikaku fails, and they are opposite mistakes.
The first is thinking during contact. The plan ran out, or the fight veered, and you stopped to decide. That pause is the death Lovret warned about — the man who thinks, during a fight, dies.1 The diagnostic sign is internal narration once blades are touching: any sentence in your head during contact means you've slipped back across the boundary into a place where thought kills.
The second is over-fixing on one plan. You did your thinking before — but you locked onto a single strategy instead of stocking a variety. So when the fight refused to follow your script, you had nothing on the shelf to grab, and you were forced to think mid-fight, which collapses you straight into the first failure.1 The sign here shows up before contact: a planning session that produces one clean plan instead of several rough options is already broken.
A third, subtler failure: letting duality creep back in during the delicate moments just before contact. The second you start thinking about saving yourself rather than destroying the opponent, the self has re-formed, and with it the fear.1 You've lost the fight before it began.
The load-bearing tension is internal to Lovret and he does not hide it. Earlier he states flatly that the man who thinks dies. Here he says there is a place for the mind in war.1 On the surface these contradict. Lovret's reconciliation is the time-boundary: thought belongs only before contact. "The key word here is before."1 Thinking before is planning; thinking during is dying. Same act, opposite verdicts, divided by a single line in time.
Preserve the tension rather than dissolving it, because the boundary is doing real work and a reader who flattens it loses the whole point. Keikaku is not "thinking is fine after all." It is "thinking is fine in exactly one window and lethal everywhere else."
A second tension worth keeping: the muscle-priming claim. Lovret asserts that mental review physically flexes muscles.1 That this is real motor priming, or merely felt, he doesn't establish — it's a practitioner's report, not a measurement. Open question: does the visualization advantage scale with how vividly the variety is rehearsed, or does rehearsing too many options dilute the priming?
Open question: how many strategies is the right number for the shelf? Too few and the fight veers off your map; too many and you may dilute the muscle-priming or freeze choosing. Lovret says "a variety" and "several" but doesn't fix a count.
Lovret is the sole source here, so the tension is not between authors but inside one author's system — and it is the most productive feature of the page. He builds a hard rule (think and die) and then immediately carves an exception (plan before) without softening the rule. A weaker writer would have blurred the two into "use good judgment." Lovret instead draws a sharp time-line and makes the whole chapter hang on the single word before.
The convergence inside his own corpus is with in-yō: keikaku is not a separate doctrine but the planning-phase application of the non-duality principle he treats as foundational. The planning ends in the same place all his combat thinking ends — the dissolution of the separate self. So even his most "mental" chapter resolves into no-mind. That is the consistency under the apparent contradiction: every road, including the one that starts in careful thought, ends at the empty self that cannot be afraid.
Lovret is writing a fight manual, but the structure he describes shows up wherever people must act fast under pressure, and two adjacent fields map onto it almost one-to-one.
The first handshake is to psychology, specifically motor imagery and mental rehearsal. Lovret's claim that quietly reviewing a strategy makes the body "instinctively flex the appropriate muscles"1 is a practitioner's statement of what psychology studies as motor imagery — imagining a movement activating some of the same motor pathways as performing it, priming the body to act. The structural parallel is exact: in both, the rehearsal is covert (no overt movement) yet physical (the muscle is readied). The insight the pairing produces, that neither field generates alone: psychology frames mental rehearsal as a training tool — repeat the imagery over weeks to improve a skill. Lovret reframes it as a just-in-time tool — rehearse in the final minutes precisely to warm the exact muscles this fight will need, then discard the thinking. The vault gains a distinction psychology rarely draws: rehearsal as long-run skill-building versus rehearsal as last-second priming. The pilot's checklist is the same trick — you don't run it to learn flying, you run it minutes before takeoff to have the responses warm.
The second handshake is to behavioral-mechanics, specifically pre-commitment and deciding in advance. Keikaku's core move — do all your deciding before the moment, so that during the moment you act without deciding — is the warrior version of pre-commitment: bind your future choices now, when you are calm, so the pressured self never has to choose. The structural parallel: both recognize that the in-the-moment self is the worst decider — hijacked by speed and fear in the fight, by impulse and emotion in the behavioral case — and both solve it by moving the decision upstream to a cooler self. The insight the pairing produces: behavioral-mechanics usually pre-commits to a single fixed course (the rule, the contract, the locked door) and relies on rigidity for its power. Lovret pre-commits to a variety and refuses to fix on one, because his domain — live combat — punishes rigidity. So the vault learns that pre-commitment has two flavors split by how predictable the environment is: lock to one when the future is stable, stock a shelf when the future will veer. The "never become fixed on one strategy"1 line is a direct correction to naive pre-commitment.
A quieter third connection runs to the same author's daishō principle: both keikaku and daishō are about fitting the situation rather than imposing a fixed response — keikaku by stocking variety, daishō by sizing your spirit to the space. Together they form Lovret's anti-rigidity pair. See Daishō, Large and Small.
The Sharpest Implication. The deepest move here is that careful thinking and no-mind are not opposites — they are sequential. You think hardest precisely so you can think least when it counts. The discipline is not "stop thinking" or "think more"; it is knowing the exact line where one must hand off to the other, and never crossing it backward. Most people fail not because they think too much or too little, but because they think at the wrong time — frozen and deciding when they should be empty and moving.
