Yilin Verse
南行求福，與喜相得。封受上賞，鼎足輔國。
Journeying south to seek blessings; meeting with good fortune. Enfeoffed and granted the highest reward; a tripod leg supporting the state.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
A lake upon a mountain, and the journey south brings fortune. Traveling southward in search of blessing, one meets joy along the way. Enfeoffment follows with highest honors, and the recipient supports the state like one leg of a three-legged cauldron. The 'tripod's foot supporting the kingdom' (鼎足輔國) evokes the image of the three great ministers who uphold the throne — a metaphor drawn from the bronze ritual cauldron's three legs. From Influence to Duration, the mountain's momentary responsiveness becomes the enduring constancy of thunder and wind reinforcing each other. What begins as an auspicious encounter solidifies into lasting institutional support. The transformation captures how a single resonant meeting — south, toward warmth and light — can establish a relationship that endures across the span of a reign.
