Yilin Verse
東壁餘光，數暗不明，主母嫉妬，亂我業事。
The lamp on the eastern wall sheds its last light; dim and dark, it does not shine. The chief wife, consumed by jealousy, throws our affairs into ruin.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder above heaven fades to a residual glow on the eastern wall — a light too dim to illuminate, its numbers exhausted and its brilliance spent. The mistress of the house, consumed by jealousy, disrupts the household's affairs and livelihood. The eastern wall's fading light suggests a once-prosperous domain now declining, while the jealous matriarch accelerates the ruin from within. From Great Power to Duration, thunder and wind persist together in Heng, the image of standing firm without changing course. The transformation is bitterly ironic: Duration demands constancy, but what endures here is the mistress's jealousy itself — a corrosive force that becomes permanent, turning the household's constancy into a prison of chronic sabotage.
