Work on What Has Been Spoiled (Hexagram 18)

What this is

The mountain over the wind: decay that has set in because something was neglected, and the wind of corruption stilled beneath the immovable. Gu is Work on What Has Been Spoiled, the figure of repair, the courage to address rot that earlier generations let fester. Hexagram 18, 蠱 (Gǔ): the upper trigram Gen (Mountain, ☶) over the lower trigram Xun (Wind, ☴); its six lines, read from the bottom upward, give the figure ䷑.

What it governs

It governs the remedy of decay, the repair of what was corrupted by neglect, the hour that calls for reform. In the Oracle it presides over the day for confronting old problems honestly and beginning the labour of restoration.

Its properties

Its image is the wind blocked at the foot of the mountain, breeding the stagnation of spoiled things; the character gu shows worms in a bowl. The virtue is the resolve to face inherited rot and undertake its cure; its movement reform after careful preparation. The shadow is the avoidance that lets decay deepen, or the rash reform that tears down without first understanding how the rot began.

Where else it appears

The cleansing of corruption is named wherever renewal demands first a reckoning. Gu is the cleansing of the temple, the Augean stables that Hercules turned the river to wash clean, the alchemist's putrefaction that must be worked through before the new can form. Worms in the bowl are the hidden faults long refused.

Where you meet it on the Oracle

It appears as the day's I Ching hexagram. Drawing Work on What Has Been Spoiled marks a day for repair: identify the neglected rot, understand its cause, and begin the patient work of setting it right. Read it as both warning and opportunity, decay can be cured if faced. The Oracle's own note on this figure: “Wind beneath Mountain — work on the decayed; correct what was neglected.”

Why it matters

This figure matters because what is left untended does not stay still, it spoils, and the longer it is ignored the harder the cure. It asks you to take up the unglamorous labour of repair, to face inherited faults rather than pass them on further decayed.
