Yilin Verse

喜來如雲,嘉福盈門。眾才君子,舉家蒙懽。

Joy arrives like gathering clouds; blessed fortune fills the gate. Worthy gentlemen of talent; the whole household basks in delight.

— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE

Commentary

Thunder doubled meets mountain over earth: shock transforms into the slow stripping of Splitting Apart. Yet the verse is entirely auspicious — joy arrives like clouds, blessings fill the gate. Talented gentlemen gather, and the whole household shares in delight. The paradox is deliberate: Splitting Apart, the hexagram of erosion, here produces abundance. Mountain resting on earth, the upper erodes toward the lower, redistributing what was concentrated above. From The Arousing to Splitting Apart, the shock that dislodges the mountain sends its wealth cascading downward. What looks like dissolution from above is generosity when viewed from below. The household that receives this avalanche of blessings benefits precisely from the splitting apart of what was hoarded on high.
