Yilin Verse
百足俱行，相輔為強。三聖翼事，國富民康。
A hundred feet walk together; supporting each other in strength. Three sages assist the throne; the state is rich, the people healthy.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Wind stirs above the lake as a hundred feet march in unison, each supporting the others in collective strength. Three sages attend to governance, and the state prospers while the people live in health and contentment. The centipede (百足) is proverbial for coordinated movement — many legs working as one body. The 'three sages' (三聖) likely refers to the founding trio of the Zhou dynasty: King Wen, King Wu, and the Duke of Zhou, whose combined civil, martial, and administrative virtues built the golden age. From Inner Truth to the Joyous, sincerity meets the doubled lake — friends gathering to study and share. Joy in its highest form is not solitary pleasure but communal flourishing, many voices in concert, many feet in step.
