Yilin Verse
雲夢大藪，嘉有所在；虞人共職，驪駒樂喜。
The great marsh of Yunmeng -- fine things dwell within. Gamekeepers share the duties; the young black horse is glad.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind beneath the mountain opens into the great marshes, and the transformation ignites as fire within the lake — the radical renewal of Revolution. The Yunmeng marshes, Chu's vast wilderness, harbor game and treasure in abundance. The wardens share their duties, and the young black horse prances with delight. Yunmeng was the legendary hunting ground of the Chu kings — a wild paradise teeming with life, managed by royal gamekeepers (虞人). The spirited colt suggests untamed energy channeled through proper stewardship. From Work on the Decayed to Revolution, the corrupt old order gives way to something fundamentally different. Fire within the lake: opposing elements that demand transformation. The wildness of Yunmeng is not chaos but a new order waiting to be declared.
