Yilin Verse
下田陸黍，萬華生齒。大雨霖集，波病潰腐。
Millet planted in lowland fields, ten thousand shoots sprout with life. But heavy rains gather and flood; blight and rot spread through all.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Paired lakes shimmer, but the low-lying fields tell a different story. Millet is planted in the lowlands, ten thousand shoots sprout teeth of grain, yet heavy rains gather in torrents, flooding and rotting the crop. What began as abundance ends in waterlogged ruin. From The Joyous to Treading, the verse warns of misplaced confidence. Treading's image — heaven above, lake below — insists on proper distinctions between high and low. The farmer who plants in bottomlands invites the very disaster he courts. Joy without discernment plants in the wrong field; only by recognizing where one truly stands can one tread safely past the tiger.
