The Judgment
Enthusiasm. It furthers one to install helpers and set armies marching. The time is right because an eminent person acts in harmony with the spirit of the people. Energy rises and finds direction.
The Lines
Line 1
Enthusiasm that expresses itself. Misfortune. Enthusiasm that announces itself—showing off, calling attention—this brings bad results. Display undercuts the power.
Line 2
Firm as stone. Not waiting till the end of the day. Perseverance brings good fortune. Knowing when to stop before excess—recognizing limits early. This grounded awareness is correct.
Line 3
Looking upward for enthusiasm brings regret. Delay brings regret. Looking elsewhere for what must come from within—or hesitating when the moment requires action. Either way, regret.
Line 4
The source of enthusiasm. Great achievement. No doubt—friends gather like hair clasped in a pin. You are the origin of the energy. Others collect around you naturally. Doubt has no place here.
Line 5
Persistently ill, yet never dies. Pressure sustained indefinitely—somehow surviving without thriving. The enthusiasm meets constant resistance but endures.
Line 6
Deluded enthusiasm. But if it changes after completion, no blame. Enthusiasm based on illusion—yet if realization comes after the action, no blame remains. You can learn from completed mistakes.
Yilin: Forest of Changes
From Jiao Yanshou's Forest of Changes (焦氏易林) — the verse for Hexagram 16 in its unchanging form. A Han dynasty collection of four-character verses interpreting every hexagram transformation.

冰將泮散,鳴雁噰噰;丁男長女,可以會同。生育聖人。
Ice is about to melt and scatter; geese honk in harmonious chorus. Grown men and elder daughters may now come together. They shall give birth to a sage.

Thunder surges from the earth as ice begins to thaw and migrating geese cry out in chorus. Young men and women may now gather together freely, and a sage shall be born. The verse celebrates the return of spring: frozen stillness gives way to movement, birdsong fills the air, and the social and biological cycles resume. The honking geese signal the season of courtship and assembly. From Enthusiasm to Enthusiasm — the hexagram returns to itself, and appropriately the verse captures the purest expression of its nature: communal joy, fertile union, cosmic renewal. When the pattern holds steady, its inherent energy simply manifests as what it always was — the earth trembling with new life.
中文注释
雷出地奮,豫之本體。冰將泮散,春回大地;鳴雁噰噰,候鳥歸來。丁男長女可以會同——春社之禮,男女相遇。生育聖人——至善之兆。此為豫卦自變之辭,故表達其最純粹之本質:雷出地奮,先王作樂崇德。冰消雁鳴為春之序曲,人倫相會為禮之根本,聖人之生為天地之大慶。卦體不變,則能量自然呈現為其本來面目——大地震動,萬物新生。
