遯

Dun is not cowardice. It is the strategic preservation of what matters by withdrawing before inferior forces consume it. The hexagram shows Heaven (Qian) above Mountain (Gen) — the creative power ascending beyond the reach of what advances from below. Two yin lines press upward from the base, representing the encroachment of small-minded forces that cannot be fought directly. The judgment says simply 亨。小利貞 — "success; in small matters perseverance furthers." The qualifier 小 is crucial: this is a time when only modest, contained action serves. Grand initiatives are structurally impossible. The Image text delivers the hexagram's operational logic: 君子以遠小人，不惡而嚴 — "the superior person distances from inferior people, not with anger but with gravity." This is the essential distinction between retreat and flight. Flight is reactive, panicked, governed by the thing fled from. Retreat is deliberate, self-possessed, governed by what must be preserved. The six lines track this with precision: the initial line warns against retreating too late (遯尾厲 — "at the tail in retreat, dangerous"), while the top line celebrates retreating freely (肥遯无不利 — "rich retreat, nothing unfavorable"). Between these poles, the third line shows the specific danger of half-retreat — 係遯, "halted retreat" — when attachment to what should be left behind compromises the withdrawal. The goal of Dun is not to win but to ensure that what deserves to survive does survive. The hexagram regulates the relationship between timing and integrity. Power that engages inferior forces on their terms becomes inferior itself. The mountain stands still while heaven rises beyond it — not because heaven lacks strength, but because contact with what rises from below would contaminate rather than correct. Retreat creates the distance that preserves the possibility of return.
