Yilin Verse
月趍日步，周遍次舍。歷險致遠，无有難處。
Moon by month and sun by day, circling through each lodge in turn. Traversing danger to reach the far; nowhere too difficult to pass.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Lake risen above heaven yields to thunder surging from the earth. The moon races and the sun strides, circling through every lodging in turn. Traversing dangers to reach distant goals, nowhere is impassable. The celestial bodies follow their ordained courses without hesitation, passing through every degree of the zodiac. No terrain — however perilous — can halt their progress. From Breakthrough to Enthusiasm, decisive action ignites the joyful momentum of thunder breaking free from the earth. The image is one of irresistible forward motion sustained by cosmic rhythm. Where Breakthrough cuts through a single obstacle, Enthusiasm carries that energy into continuous, exuberant advance across the entire circuit of heaven.
