Yilin Verse
蓄積有餘，糞土不居。
Stores accumulated in surplus; dung and soil lie untouched.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Paired lakes face fire above and lake below — Opposition, where apparent contraries coexist. Stores are accumulated in surplus, but dung and refuse are not permitted to remain. The verse is strikingly brief: wealth abounds, filth is expelled. The image suggests rigorous sorting — keeping what has value, discarding what pollutes. From The Joyous to Opposition, the unity of joy splits into necessary discrimination. Fire rises, lake descends; they move apart yet illuminate each other. The gentleman uses this pattern to find commonality within difference. Accumulated wealth that refuses to harbor corruption embodies this principle: prosperity and purity are opposites that must coexist.
