Yilin Verse
利在北陸。寒苦難得。憂危之患，福為道門。商叔生存。
Profit lies in the northern wastes; cold and bitter, hard to obtain. Perilous worry and dread; fortune becomes the gate of the Way. Shang Shu survives.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Lake over wind erupts into doubled thunder — the Arousing, the shock that stirs renewal. Profit lies in the northern quarter, cold and hard to obtain. Worry and peril threaten, yet fortune becomes the gateway of the Way. The Shang uncle survives. 'The northern quarter' (北陸) is the winter sun's position, the place of maximum cold and hardship. The 'Shang uncle' (商叔) may refer to the Viscount of Wei (Weizi), the Shang prince who survived the dynasty's fall and was enfeoffed at Song. His survival through terrible upheaval embodies the verse's arc: peril does not destroy but leads to fortune's door. From Great Exceeding to the Arousing, the collapsing beam meets the double thunderclap. Shock upon shock — yet within the tremor, the survivor finds the Way.
