Yilin Verse
堯舜在國，陰陽和得。涿聚衣常，晉人無殃。
Yao and Shun rule the land; yin and yang find their balance. Gathering garments in proper order; the people of Jin suffer no harm.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
A lake upon a mountain, and the golden age is invoked. Yao and Shun preside over the realm, yin and yang achieve perfect harmony. The people of Zhuo gather in their everyday garments, and the people of Jin suffer no calamity. The verse names the two supreme sage-kings to evoke an era when governance required no force because the cosmos itself was in balance. 'Yin and yang harmonized' is the highest possible political praise in classical thought. From Influence to Great Power, the mountain's receptive feeling becomes thunder rolling above heaven — explosive yang energy surging forward. Under Yao and Shun, such power needs no coercion; it manifests as natural abundance. The transformation suggests that genuine mutual influence, perfected through virtue, unleashes power far greater than force alone could generate.
