Yilin Verse
耳如驚鹿,不能定足。室家分散,各走匿竄。
Ears alert like a startled deer, unable to steady its footing. The household scatters apart; each flees and hides in secret.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind and thunder bestow increase, but the transformation leads to fire and thunder — the decisive bite of Biting Through, here experienced as the terror of being bitten. Ears prick like a startled deer, feet unable to find stable ground. The household scatters, each member fleeing and hiding in different directions. The imagery is visceral: a family unit disintegrating under sudden threat, every member reverting to animal instinct. The startled deer is pure flight response — no reasoning, no plan, only terror. From Increase to Biting Through, the verse captures the moment when accumulated tension snaps. Lightning and thunder bring clarity through shock; what cannot hold together is violently separated. The increase that should have strengthened the household instead amplified the tensions that finally tore it apart.
