Trigram Changes
Yilin Verse
雷行相逐，無有休息；戰於平陸，為夷所覆。
Thunder chases thunder without cease. They battle on the open plain; overwhelmed by the foreign host.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder chases thunder without rest — relentless pursuit with no respite. An army fights on the plain of Pinglu and is overrun by the Yi barbarians. The doubled thunder of the verse mirrors Enthusiasm's trigram composition, but here the energy is misdirected: instead of joyous mobilization, it becomes exhausting pursuit that ends in defeat. Pinglu offers no defensive advantage, and the overconfident army is overwhelmed. From Great Possession to Enthusiasm, fire over heaven gives way to thunder erupting from the earth. The verse warns that enthusiasm without strategic ground collapses into rout. The same explosive energy that inspires can destroy when it meets a better-prepared adversary on open terrain.
