Yilin Verse
太一置酒，樂正起舞。萬福攸同，可以安處，綏我齯齒。指空無餌，不利為旅。
Tai Yi sets out wine; the music master rises to dance. Ten thousand blessings converge as one; one may dwell in peace. He comforts our aged teeth. Yet pointing at emptiness without bait, it is not favorable for travel.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Heaven stored within the mountain erupts as thunder in heaven — Great Power. Taiyi, the Supreme One, hosts a grand feast; the Master of Music rises to dance. Ten thousand blessings converge, and one may dwell in peace, easing into serene old age. Yet the verse turns: the hook is cast into empty water with no bait, and travel brings no gain. Taiyi, the supreme celestial deity of Han cosmology associated with the pole star, presides over cosmic order. When accumulated virtue is celebrated at the divine level, earthly happiness follows. But the closing warning qualifies the jubilation: spiritual fullness does not guarantee material success. From Great Taming to Great Power, the mountain's stored heaven becomes thunder shaking the heavens — overwhelming force that must still respect limits.
