Yilin Verse
杜飛門啟，憂患大解，不為身禍。
The blocked gate flies open; worry and trouble dissolve at once. No harm befalls the person.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Fire within the lake transforms into thunder and fire together — Abundance, where power and clarity unite at their zenith. 'Du flies off and the gate opens; worries and calamities dissolve utterly, bringing no harm to oneself.' The character 杜 (du) means 'to block' or 'to close' — when the blockage flies away, the gate opens freely. This is revolutionary liberation at its most concentrated: the obstacle simply vanishes, and the floodgates of relief swing wide. From Revolution to Abundance, the transformation captures the apex of revolutionary success: the moment when obstruction lifts, light and power converge, and one walks through the open gate unscathed.
