Yilin Verse
行觸夫忌，與司命牾。執囚束縛，拘制於吏，幽人有喜。
Actions offend the taboo; clashing with the Lord of Fate. Seized and bound in fetters; restrained by officials. The imprisoned one finds joy.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind stirs above the lake, but one's actions collide with taboo, offending the Lord of Fate (司命). Seized, bound, and handed over to the magistrate — yet the imprisoned one finds joy. The verse inverts expectation: transgressing the cosmic authority that governs life and death results in arrest, but the prisoner somehow discovers gladness in confinement. The phrase 'the confined one has joy' (幽人有喜) quotes the I-Ching's own Zhongfu hexagram, line nine-two. From Inner Truth to the Arousing, sincerity confronts doubled thunder — shock upon shock. The Arousing's gift is precisely this: the first thunderclap terrifies, but the second brings the laughter of one who has passed through fear and emerged whole.
