Yilin Verse
車雖駕，兩靷絕；馬欲步，雙輪脫。行不至，道遇害。
The cart may be harnessed, but both traces snap; the horse would step forward, but both wheels break free. The journey fails to reach its end -- on the road, one meets with harm.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Fire and thunder enforce the law, and here the entire mechanism of movement collapses. The carriage is harnessed, but both trace-ropes snap. The horse tries to step forward, but both wheels fall off. The journey never reaches its destination; on the road, harm is encountered. Every component fails simultaneously — ropes, wheels, progress, safety — a cascade of mechanical breakdown. From Biting Through to The Arousing, doubled thunder should galvanize action. Yet the verse shows arousal without capacity: the impulse to move exists, but every means of movement has disintegrated. The shock of thunder without a vehicle to carry it forward becomes pure futility — energy with no channel, will with no way.
