Wind following wind, entering every crevice: Xùn is the gentle — penetration by persistence, influence that succeeds not by force but by ceaseless, unspectacular repetition.
Its power is cumulative: commands spread abroad and repeated, roots worked into hidden ground. Its failure modes are its own excess — penetration repeated past decision into dithering, searching carried under the bed into obsession. Gentleness needs a spine: somewhere, the wind must also decide.
問Xùn works on the heart the way wind works on stone: small kindnesses repeated, understanding accumulated in layers, influence no single gesture could achieve. It favors patient re-approach over confrontation. Its warning is equally intimate — endless re-analysis of the relationship, the third line's repeated penetration, dissolves the very resolve it was meant to inform.
Professionally, Xùn is influence by iteration: the idea reintroduced until it becomes the room's assumption, the standard upheld daily until it becomes culture. Investigate hidden roots of problems thoroughly — but once, with resolve, not forever. Its calendar counsel is durable: weigh three days before the change, verify three days after.
Inwardly, Xùn is the gentle discipline: habits that penetrate character through sheer dailiness rather than willpower storms. It also names the shadow — introspection become excavation, turning the same soil until nothing can grow. Enter yourself the way wind enters a valley: thoroughly, then move on.
A line speaks only when it is a changing line in your own casting.
