Decay

Repairing what has spoiled requires more than clearing away visible damage. The judgment names great success, a difficult crossing, and three days before and after the jiǎ day. That calendrical phrase has received different explanations and should not be turned into a universal seven-day productivity formula. Modern repair needs diagnosis before intervention and follow-through afterward, while remaining honest about causes, responsibility, and limits.

The judgment announces great success and a favorable crossing, then adds a calendrical phrase: three days before the jiLj day and three days after. JiLj is one of the heavenly stems, and the phrase has been interpreted in several ways by traditional commentators. Some read it as an instruction to prepare before undertaking repair and to follow through afterward. Others connect it to specific days in the ancient calendar on which corrective action was considered appropriate. The text does not itself specify which reading is correct, and the phrase should not be turned into a universal seven-day productivity formula.

Mountain above Wind forms the hexagram figure. Traditional commentary develops images of disorder beneath a stopping point and of renewing people or conduct. The name 蠰 carries connotations of decay, spoiling, and the corrosion that comes from neglect. In the sequence of hexagrams, this one follows Holding Together and precedes Approach, suggesting that after a period of consolidation the question of what has been allowed to deteriorate must be faced.

Wind beneath Mountain offers a vivid structural image. Wind erodes, and Mountain stands firm—but only so long as the stone holds. When internal rot goes unattended, even the sturdiest mass will give way. The decay in question is not sudden catastrophe; it is the slow work of time, attention, and care withdrawn from what needed them.

Modern repair should be neither cosmetic nor punitive. Before acting, identify what failed, who was affected, and which incentives or routines allowed the failure to persist. Then make the smallest intervention capable of changing the cause, not merely the appearance. Afterward, verify whether the repair holds and whether it created new burdens elsewhere. Some damage cannot be restored by the person who caused it alone; accountability may require consent, compensation, outside expertise, or separation. The hexagram supports sustained remediation rather than confidence that every decay can be reversed.
