Hexagram 18 — Work on the Decayed (蛊)
A clear, modern reading of I Ching hexagram 18—Work on the Decayed (Gǔ): Repair what has been neglected.
Gu is decay needing repair — wind under the mountain, stagnation breeding rot. Stir people and cultivate virtue; reform needs careful planning before and after the turning point.
The Judgment
元亨，利涉大川。先甲三日，后甲三日。
Yuán hēng, lì shè dà chuān. Xiān jiǎ sān rì, hòu jiǎ sān rì.
“Supreme success. It furthers to cross the great water. Three days before and three days after the turning point.”
In plain terms: Repair what has been neglected.
The Image
山下有风，蛊；君子以振民育德。
Shān xià yǒu fēng, gǔ; jūnzǐ yǐ zhèn mín yù dé.
“Wind beneath the mountain — the noble person stirs the people and cultivates virtue.”
The Image invites us to translate the hexagram's symbolism into practical conduct—not superstitious fortune-telling.
