Yilin Verse
鬱怏不明，陰積無光。日在北陸，萬物彫藏。
Gloomy and unclear; dark clouds gather, blocking the light. The sun lies in the northern depths; the ten thousand things wither and hide.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder beneath heaven falls silent as the world sinks into midwinter darkness. The air hangs heavy and joyless, yin accumulates without a glimmer of light. The sun travels along the northern arc — the winter solstice path — and all living things wither into hibernation. This is nature at its most contracted: the Yilin renders the seasonal image with precise astronomical vocabulary. From Innocence to Youthful Folly, the transformation follows nature's logic. When heaven's thunderous energy retreats behind dense clouds, a spring below a mountain remains hidden — pure potential not yet understood. Meng's darkness is not malice but ignorance awaiting instruction, the deep winter before the first lesson breaks through.
