Hexagram 18: Work on What Has Been Spoiled Changing to Hexagram 41: Decrease

I Ching casting meaning · Gu → Sun

The fix turns out to be subtraction. Moving from spoilage into Decrease, the reading is plain: this situation got sick from too much—too many commitments, features, expenses, opinions—and the cure is a sincere, deliberate less. Not austerity theater; a real offering-up of the excess. Cut the thing you're oddly proud of carrying, because that pride is part of the rot. What makes this hexagram hopeful is its arithmetic: decrease offered willingly at the bottom becomes increase at the top. Simplicity here concentrates everything that remains. Pick the one load you can put down this week without the world ending, put it down completely, and watch what the freed capacity repairs by itself.

A casting that moves from Work on What Has Been Spoiled into Decrease 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 and 3 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 Decrease.

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 41, Decrease

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Work on What Has Been Spoiled gives way to Decrease (Sun) — Lake below Mountain. The advice that belongs to this outcome: Cut one thing deliberately and give the savings to what matters most.
