Yilin Verse
月走日步，逃不同舍；夫妻反目，主君失位。
Moon racing, sun striding, fleeing to separate lodgings; husband and wife at odds, the lord loses his position.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder erupts from the earth, but the moon races and the sun walks — they flee in different directions and never share the same lodging. Husband and wife turn against each other; the ruling lord loses his seat. The celestial bodies in discord mirror domestic and political breakdown: when the two luminaries that should govern day and night cannot coordinate, all order dissolves. From Enthusiasm to Opposition, the transformation fits precisely. Fire above and lake below — heat rises while water sinks, two forces that see the same world differently. Opposition's image is inherent divergence, and the verse dramatizes this as cosmic estrangement: not just disagreement but fundamental incompatibility of path, where each party flees what the other approaches.
