Yilin Verse
彫葉被霜，獨蔽不傷。駕入喜門，與福為婚。
Carved leaves coated in frost; alone sheltered, unharmed. Driving through the gate of joy; wedding with blessing itself.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Mountain over thunder gives way to thunder over mountain — Small Exceeding, the bird that must descend rather than ascend. Withered leaves are struck by frost, yet one alone is sheltered and unharmed. The carriage enters the gate of joy, and fortune becomes one's bride. The frost-bitten leaves represent general devastation — the season's killing breath — yet a single leaf survives, protected by some unseen grace. From Nourishment to Small Exceeding, the transformation is modest and precise: the small bird does not fly too high but stays low and safe. The surviving leaf embodies this principle — exceeding just enough to endure, not so much as to expose itself. Through small, careful excess in humility, one enters the gate of happiness unscathed while others fall.
