Yilin Verse
張鳥關口，舌直距齒。然諾不行，政亂無緒。
A bird snared at its open mouth; tongue pressed flat against the teeth. Promises and oaths go unfulfilled; governance falls to chaos, without order.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Mountain over thunder gives way to thunder over fire — Abundance, the zenith of power and clarity. A net is stretched at the bird's beak, the tongue pressed rigid against the teeth. Promises are not kept, and governance descends into disorder without any thread of coherence. The image of the mouth physically restrained — tongue locked, beak netted — inverts Nourishment's core function. The mouth that should both feed and speak truth is silenced and trapped. From Nourishment to Abundance, the transformation should bring thunder and lightning illuminating all things, yet here the mouth's blockage prevents the lightning's judgment from being articulated. Abundance without honest speech is chaos masquerading as plenitude.
