Yilin Verse
鴻飛在陸，公出不復。仲氏任止，伯氏客宿。
The wild goose flies over land; the lord departs and does not return. The second brother stays at his post; the eldest brother lodges abroad.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Water hidden within the earth dispatches its forces, and a wild goose alights upon the dry land as a lord departs and does not return. The second brother settles in place while the eldest becomes a sojourner. The 'goose on dry land' echoes the Yijing's Gradual Development hexagram — a bird far from water, exposed and vulnerable. The verse distributes the brothers' fates unevenly: one stays rooted, the other is cast into permanent exile. From The Army to The Arousing, doubled thunder shakes the foundations. The sudden shock separates those who should remain together — the army's cohesion shatters into individual fates, each brother absorbing a different tremor of the upheaval.
