Yilin Verse
北陰司寒，堅冰不溫；凌人情怠，大雹為災。
The northern yin governs cold; hard ice that never warms. The ice keeper's spirit grows idle; great hail brings disaster.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven and earth stand sealed as the northern darkness governs the cold. Hard ice refuses to warm, the ice-keepers grow negligent, and massive hailstones bring disaster. From Standstill to Obstruction, Pi's frozen communication deepens into Jian's mountain with water above — the path blocked by perilous terrain in every direction. The verse intensifies Pi's winter imagery: not just separation but active freezing, not just stillness but destructive ice. The 'ling ren' (ice-keepers) were officials charged with managing stored ice; when they become negligent, the cold they were supposed to control runs wild. Jian counsels turning inward — 'reflecting on oneself and cultivating virtue' — because when external conditions are this hostile, only inner preparation preserves.
