Yilin Verse
履泥污足，名困身辱；兩仇相當，身為疾病。
Treading through mud, feet soiled; reputation ruined, body shamed. Two rivals matched against each other -- the body falls prey to sickness.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind over earth treads into mud and finds no clean ground. Walking through mire dirties the feet, reputation is trapped, and the body suffers disgrace. Two enemies are evenly matched, and the body falls into illness. The verse presents a world where every step contaminates — there is no path that does not soil. Evenly matched foes suggest stalemate rather than resolution, and the body breaks down under prolonged conflict. Water over mountain forms Obstruction, where dangerous waters pool atop steep terrain. From Contemplation to Obstruction, observation discovers impasse: the view from the summit reveals only perilous water above and steep cliffs below. When the footing is treacherous everywhere, the sage turns inward to cultivate virtue rather than pressing forward.
