Yilin Verse
氈裘羶國，文禮不飭；跨馬控弦，伐我都邑。
A land of felt robes and rank mutton, where rites and courtesy are not observed; astride horses, drawing bows, they attack our capital.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder erupts from the earth, but what rises is not music — it is mounted raiders from the northern steppe. Clad in felt and furs, smelling of mutton, knowing nothing of rites or written culture, they cross the frontier on horseback with bows drawn, attacking the capital itself. The verse paints the classic Chinese fear: the barbarian invasion that overwhelms civilization's defenses. From Enthusiasm to Waiting, the transformation is grimly apt. Waiting's image is clouds gathering over heaven — danger approaches but has not yet struck. The raiders' assault transforms joyful preparedness into anxious vigilance, and the proper response is not panic but the composed readiness that Waiting demands: one must nourish oneself and bide the time.
