Yilin Verse
彭君為妖，暴龍作災。盜堯衣裳，聚跖荷兵。青禽照夜，三日夷亡。
Lord Peng works his evil; the violent dragon brings disaster. Stealing the robes of Yao, gathering bandits like Zhi under arms. The blue-green bird illuminates the night; in three days, the Yi are destroyed.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Fire within the lake gives way to the lake submerging wind — Great Exceeding, where the structure buckles under extraordinary pressure. Peng Sheng becomes a demon; a violent dragon wreaks havoc. Someone steals Yao's robes and gathers Robber Zhi's armed bands. A blue bird illuminates the night; within three days the Yi perish. According to tradition, Peng Sheng was a strongman of Qi whom Duke Xiang ordered to murder Duke Huan of Lu, then killed to silence. His ghost later appeared as a wild boar, terrifying Duke Xiang to death. The verse layers usurpation upon usurpation: stealing a sage-king's garments to cloak banditry. From Revolution to Great Exceeding, the beam snaps when revolution is hijacked by monsters wearing borrowed legitimacy.
