I Ching · Hexagram 21 Biting Through
Hexagram 21 line 3: Biting Through, yin in the third place

I Ching 21.3
Biting on old dried meat and striking on something poisonous. Slight humiliation. No blame.
An old wrong, long neglected, which resists correction and provokes resentment when it is finally addressed. The line says to proceed anyway. The unpleasantness is the cost of having waited, not a reason to stop.
Advice. The old problem will resist and it will be unpleasant; deal with it regardless.
What changes when line 3 moves
Line 3 of Hexagram 21 is yin, a broken line. When it is cast as old yin (a 6) it flips, and the hexagram becomes Hexagram 30, The Clinging: Fire that burns by clinging to what feeds it: clarity, dependence and the care of a cow.
Read together, the reading moves from Biting Through toward The Clinging. An obstruction that must be bitten through: clear, firm, lawful action against what is in the way. Fire below, fire above: light doubled, the sun rising twice. The Clinging is the hexagram of clarity and of dependence: fire is bright, and fire exists only by holding onto what it burns. The primary hexagram describes the situation; the changing line is the point of movement in it; the resulting hexagram is where that movement leads. Both hexagrams belong to the reading, and the changing line is the hinge between them.
Line 3 in context
- Love & relationships
- The old problem will resist and it will be unpleasant; deal with it regardless. In love and relationships, Hexagram 21 reads: Something is stuck between you and it will not clear on its own. Name it plainly and deal with it. Firmness here is kindness; the obstruction left in place poisons everything around it.
- Career
- The old problem will resist and it will be unpleasant; deal with it regardless. In career, Hexagram 21 reads: An obstacle, a wrong or a person who is blocking things, and the moment to act on it decisively. Be clear about the facts, proportionate in the response, and do not let it drag. Justice, not vengeance.
- Money
- The old problem will resist and it will be unpleasant; deal with it regardless. In money, Hexagram 21 reads: A dispute, a debt or a bad arrangement that needs resolving by firm action. Get the facts straight, act through proper channels, and bite through rather than nibbling.
- A decision
- The old problem will resist and it will be unpleasant; deal with it regardless. In decisions, Hexagram 21 reads: Decide firmly and act. The reading supports the decisive option, and it conditions it on fairness and clarity: know exactly what the obstruction is before you bite.
