The Six Lines

Line 1: Line 1: Enthusiasm that shows itself brings misfortune.

Line 2: Line 2: Firm as a rock. Not a whole day. Perseverance brings good fortune.

Line 3: Line 3: Enthusiasm that looks upward creates remorse. Hesitation brings remorse.

Line 4: Line 4: The source of enthusiasm. He achieves great things. Doubt not. You gather friends around you as a hair clasp gathers the hair.

Line 5: Line 5: Persistently ill, and still does not die.

Line 6: Line 6: Deluded enthusiasm. But if after completion one changes, there is no blame.

Modern Application

Hexagram 16 is about the power of collective energy and shared purpose. Thunder emerging from the earth represents the explosive release of pent-up creative force. The ancient kings used music to channel this energy — enthusiasm needs form and direction. The hexagram distinguishes between authentic enthusiasm (which inspires and mobilizes) and false enthusiasm (which is performative or deluded). In modern terms, Enthusiasm applies to team motivation, public speaking, launching initiatives, and the art of rallying people around a vision. The warning is clear: enthusiasm that merely shows off exhausts itself; genuine enthusiasm comes from substance and compels action.
