Pu — simplicity and the uncarved block

Return regularly to an unconditioned, open state before adding complexity or opinion.

Why it works

The mind accumulates assumptions, preferences, and fixed narratives that filter perception. Pu ("uncarved block") is the practice of temporarily releasing those overlays — sitting with something as it is rather than as you categorize it. This is structurally identical to mindfulness’s beginner’s mind, and reduces cognitive rigidity by loosening the automatic application of habitual frames.

How to do it

1. Pick one daily routine task and do it as if for the first time, noticing what you actually observe rather than what you expect.
2. Before an important conversation, pause and drop any "I already know how this will go" story.
3. Simplify one area of your life — physical space, calendar, or commitments — by removing what is not essential.
4. Sit quietly for five minutes without agenda; resist the urge to plan, review, or evaluate.

Evidence

Beginner’s mind — the closest empirical analog to pu — is a component of mindfulness training. Mindfulness’s effects on reduced cognitive rigidity and enhanced psychological flexibility have observational support, though pu as a distinct practice has not been directly tested. (mechanistic)

Pu is a philosophical concept; the mechanism (reducing habitual mental overlay) is consistent with mindfulness research, but no direct trial of "pu practice" exists.

Common mistake

Treating simplicity as asceticism — the goal is not to strip away all preference, but to notice when accumulated complexity obscures clear seeing.
