Hexagram 14: Possession in Great Measure Changing to Hexagram 21: Biting Through

I Ching casting meaning · Da You → Shi He

Something hard has gotten into the machinery — Biting Through says a real obstruction now sits between your resources and their proper flow: a broken rule, a violation everyone's tiptoeing around, a knot that only decisive pressure will crack. Politeness and patience won't fix this one. Bite: name the problem plainly, make the call, enforce the consequence — cleanly, once, without cruelty, through whatever proper channels apply. Hesitation is the true threat here; an obstruction this defined hardens when tolerated, and it jams everything else you own behind it. Handle it, and the whole estate moves freely again. One decisive afternoon of discomfort, traded for a season of unobstructed operation.

A casting that moves from Possession in Great Measure into Biting Through 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 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 Possession in Great Measure into Biting Through.

The situation: Hexagram 14, Possession in Great Measure

Abundance with responsibility. Much is yours — handle it well.

Fire high in the sky, lighting everything below — this is the big-harvest hexagram. Resources, attention, opportunity: you have more than usual, and more than most. The reading here is mostly warning disguised as celebration. Abundance attracts gravity — rivals, flatterers, your own complacency. Stay generous and stay sharp; hoarding corrodes it and arrogance burns it down faster. Use the surplus on things that matter: the people who got you here, the work that outlasts the moment. Plenty is a test of character. Pass it, and this becomes a foundation instead of a peak.

Structurally, Possession in Great Measure is Heaven below Fire — the inner state meeting the outer condition. That pairing is the lens for everything above.

Where it's heading: Hexagram 21, Biting Through

An obstruction must be bitten through. Decide and enforce.

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Possession in Great Measure gives way to Biting Through (Shi He) — Thunder below Fire. The advice that belongs to this outcome: Name the obstruction and bite through it once — firmly, fairly, finally.
