Hexagram 18: Work on What Has Been Spoiled Changing to Hexagram 10: Treading

I Ching casting meaning · Gu → Lü

Careful — you're repairing something while standing on it. Treading means the spoiled situation still has teeth: touchy egos, unstable structures, a person with power who could crush the whole repair if stepped on wrong. The fix continues, but your conduct now matters as much as your competence. Move with clean manners and precise timing; correct the system without humiliating the people attached to it. Before your next intervention, rehearse exactly how it lands on the most sensitive party in the room. Respect without groveling, honesty without theater. Walk across this like the floor is glass and you'll get through unbitten — keeping the goodwill you'll need afterward.

A casting that moves from Work on What Has Been Spoiled into Treading means the situation you asked about is not static — it begins as one pattern and resolves into another. The first hexagram describes where you stand; the second describes where events are carrying you.

Highlighted in red: lines 1, 3, 4 and 5 are moving — counted from the bottom. A moving line is where the change is actually happening: it flips from yang to yin or back, and that flip is what turns Work on What Has Been Spoiled into Treading.

The situation: Hexagram 18, Work on What Has Been Spoiled

Something spoiled needs repair. Name the rot, fix the root.

Wind trapped under a mountain — stagnation that's gone stale long enough to spoil. This hexagram hands you a repair job: a project, habit, relationship, or system that used to work and now quietly doesn't, because something at the root went wrong a while ago. Surface fixes won't hold. Go find the original decision, the deferred maintenance, the thing everyone politely stopped mentioning. It's uncomfortable work with a real payoff — this decay is fixable, and fixing it releases energy that's been stuck for months. Be thorough, be honest about causes, and finish what the cleanup starts.

Structurally, Work on What Has Been Spoiled is Wind below Mountain — the inner state meeting the outer condition. That pairing is the lens for everything above.

Where it's heading: Hexagram 10, Treading
