Yilin Verse
螟虫為賊，害我稼穡；禾殫麥盡，秋無所得。
Caterpillars are the bane, ravaging our crops and grain; wheat exhausted, millet gone -- nothing gained come autumn.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder breaks from the earth, but the harvest is consumed before it can be gathered. Boring insects ravage the crops — grain exhausted, wheat gone, nothing left for autumn's reaping. The spiraling pests devour methodically, leaving the farmer with bare stalks and empty hands. From Enthusiasm to Modesty, the transformation carries a sharp lesson. Modesty's image is a mountain hidden within the earth, greatness concealed beneath humility. The insects strip away everything external — the showy grain, the promising wheat — until only the bare ground remains. What enthusiasm builds, natural forces can level; Modesty teaches that true substance lies below the surface, where no pest can reach.
