Commentary

Clouds and thunder yield to lake above thunder: initial hardship gives way to joyful following. The Supreme One rides a bay horse descending from heaven, summoning a younger son and enfeoffing him as Marquis of Lu. Taiyi, the supreme celestial deity of Han cosmology, here acts as divine patron, bestowing political destiny from above. The verse evokes the Zhou investiture tradition, where the Duke of Zhou's descendants received the fief of Lu as reward for loyal service. From Difficulty at the Beginning to Following, the mandate arrives not through human striving but through heavenly summons. Thunder rests beneath the lake; the subject follows the call with willing obedience, and what began in struggle resolves in divinely ordained appointment.
