Yilin Verse
水壞我里，東流為海；龜鳧讙囂，不覩慈母。
Water breaches our village, flowing east to the sea. Turtles and ducks cry in clamor; they cannot see their dear mother.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Earth above heaven, Peace inundated. Floodwaters destroy the village, pouring eastward into the sea. Turtles and wild ducks clamor noisily amid the ruins, and the children cannot find their mother. The scene is devastation after a flood: human habitation replaced by aquatic creatures, family bonds severed by rising waters. The mother-child separation is the verse's emotional core — chaos at its most primal. From Peace to The Joyous, paired lakes commune in mutual delight, and the gentleman gathers friends for learning. The transformation is bitterly ironic: where Joyous promises the pleasures of shared waters, this verse shows waters that shatter rather than unite. Joy requires that the lake be contained; uncontained, it becomes catastrophe.
