Something grew in the vesselWork on the Decayed
What has spoiled will not heal itself — nor collapse at once.
Gu is worms in the vessel. Decay's terror is its quietness: the structure stands, the function has hollowed, everyone has learned to make do. The judgment speaks of setting right what the father spoiled — clearing the mess left by those before you is the heir's duty and the most thankless of jobs.
Repair needs a time-scale: three days before the start, three days after. Read the whole vein before acting; watch for rebound after acting. The hasty single cut usually amputates the healthy parts too. True repair is patient: first stop the rot, then cultivate what should grow.
Practice Pick one old problem you have endured without fixing. Today take only the first step: see it completely and write it down.
