Yilin Verse
兩心不同，或欲西東；明論終始，莫適所從。
Two hearts not in accord; one would go west, the other east. Debating the matter from beginning to end, neither knows whom to follow.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder rests within the lake, but two hearts pull in opposite directions — one wishes to go west, the other east. Even after a thorough analysis of beginning and end, there is no resolution about whom to follow. The verse distills the paralysis of indecision: when two equally compelling paths diverge, rational analysis provides no tiebreaker. From Following to the Joyous, paired lakes in Dui represent shared delight through mutual discourse — friends studying and debating together. Yet this verse shows the failure mode of Dui's doubled openness: two open mouths speaking at cross purposes, each joyfully certain of a different direction, producing not consensus but stalemate. Following requires choosing; endless discussion is its own form of refusal.
