Commentary

Thunder over lake gives way to thunder over earth: the maiden's impulsive energy finds outlet in Enthusiasm's mobilizing power. For three years one chases profit, darting like a spirit, rolling east and west like a bird dodging pellets. The verse captures relentless commercial agility, a merchant who survives by speed and instinct rather than by settling anywhere. From the Marrying Maiden to Enthusiasm, the transformation channels restless movement into purposeful momentum. Thunder emerging from earth shakes the world into coordinated action, as the ancient kings used music and ceremony to unite. The merchant's bird-like evasion resonates with Enthusiasm's thunderous release: energy that cannot be contained finds its proper expression in swift, decisive movement.
