Yilin Verse
特犧孔博，日新其德；文公燎獵，姜氏受福。
The sacrificial ox is vast and fine; daily renewing its virtue. Duke Wen set fires for the hunt -- the Jiang clan received her blessing.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind beneath the mountain calls for renewal through sacrifice, and the transformation rises as wind and thunder together — the dynamic Increase of Yi. The sacrificial animals are magnificent and abundant, their virtue renewed each day. Duke Wen conducted a hunt at the blazing fields, and the Jiang consort received blessings. According to tradition, when Chong Er lingered in Qi enjoying comfort, his wife Jiang — of the Jiang clan — conspired with his advisers to get him drunk and spirit him away, forcing him to resume his quest for the Jin throne. Her decisive act secured the blessings of his eventual hegemony. From Work on the Decayed to Increase, the spoiled complacency is shattered by bold intervention. Wind and thunder magnify each other: seeing good, one moves toward it; recognizing fault, one corrects it immediately.
