Yilin Verse
瞻白因弦，駑孱恐怯。任力墮劣，如蝟見鵲。偃視恐伏，不敢拒格。
Gazing at the white, drawing the string; the weak horse shrinks in fear. Strength failing, courage flagging, like a hedgehog seeing a magpie. Cowering low in dread, not daring to resist or fight.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Paired lakes yield to thunder submerged beneath the lake — Following. A weak bow glimpses a white shape on the bowstring and quails in terror. Its strength fails, its skill falters — like a hedgehog spotting a magpie, it cowers face-down, too frightened to resist. The verse paints pure inadequacy: the archer lacks both power and nerve. From The Joyous to Following, delight dissolves into reflexive submission. Yet Following need not mean cowardice; thunder rests beneath the lake at nightfall, gathering energy in stillness. The hedgehog's posture, though fearful here, also preserves the creature. Sometimes following means knowing when not to fight.
