Hexagram 27: Nourishment Changing to Hexagram 18: Work on What Has Been Spoiled

I Ching casting meaning · Yi → Gu

Something in the pantry has gone off, and ignoring the smell won't fix it. Work on What Has Been Spoiled means the nourishment system itself needs repair — a habit, a relationship, an organization that once fed people and now quietly poisons them. Trace it to the root: what went in wrong, and for how long? This is unglamorous, necessary labor, and your words matter in it — name the rot precisely but without cruelty. Clean the shelf, throw out what's dead, restock with care. What you repair now feeds you for years.

A casting that moves from Nourishment into Work on What Has Been Spoiled 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, 2 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 Nourishment into Work on What Has Been Spoiled.

The situation: Hexagram 27, Nourishment

Watch what you feed. Nourishment reveals character.

The image is a mouth — and the hexagram asks what goes in and what comes out of yours. Nourishment is the theme: food, information, conversation, the content diet you run your brain on. Audit the intake. Are you feeding yourself things that build, or things that just fill? The same question applies to your words: what you say this week carries unusual weight in how people size you up. Nourish others well and you'll be sought after; demand to be fed constantly and you'll be managed. Choose your inputs like they become you. They do.

Structurally, Nourishment is Thunder below Mountain — the inner state meeting the outer condition. That pairing is the lens for everything above.

Where it's heading: Hexagram 18, Work on What Has Been Spoiled

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

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Nourishment gives way to Work on What Has Been Spoiled (Gu) — Wind below Mountain. The advice that belongs to this outcome: Find the root cause of one broken thing and repair it fully.
