Hexagram 21

Biting Through

Shih Ho / Shì Kè 噬嗑

Shih Ho is the hexagram of the obstacle between the teeth: something has come between what belongs together, and the jaws must close through it. An obstruction — a lie, a wrong, a usurpation, a slanderer between two people — blocks union, and gentleness alone will not remove it. The bite must be decisive: thunder's shock and lightning's clarity acting as one.

The full meaning of Hexagram 21

Overview

Shih Ho is the hexagram of the obstacle between the teeth: something has come between what belongs together, and the jaws must close through it. An obstruction — a lie, a wrong, a usurpation, a slanderer between two people — blocks union, and gentleness alone will not remove it. The bite must be decisive: thunder's shock and lightning's clarity acting as one.

The Judgment points to justice: the obstacle is dealt with not by rage but by law — clear standards, proportionate consequences, energy joined to fairness. Biting through succeeds because it is both vigorous and exact; either quality without the other fails.

The Spirit of Shih Ho

Decisiveness here is not aggression. Before the bite comes clarity — sometimes won only by first withdrawing into stillness, letting the wisdom of the Sage restore moderation, and seeing the situation for what it is. Then the action: bold, clean, without hesitation, and without hatred.

The image's "clearly defined penalties" apply inwardly too. Our own transgressions carry natural consequences — not the cosmos punishing us, but the structure of things asserting itself. Understanding penalties this way removes both self-pity when we suffer them and cruelty when we administer them.

The Shadow Side

The bite has two corruptions. Weakness: knowing the obstacle must be dealt with and endlessly deferring, until the obstruction grows teeth of its own. And ferocity: punishment carried past justice into vengeance, correction fuelled by anger rather than clarity. The one leaves the wrong in place; the other becomes a new wrong. Between them runs the narrow path of the just bite — hard enough to sever, and no harder.

Changing lines

Six line readings

Open any line for the full changing-line interpretation, including its direct answer, action guidance, and direction of change.

Line 1

Feet in the Stocks

His feet are fastened in the stocks, hiding his toes. No blame.

The first offence, met with the first, mildest penalty: the stocks stop the feet before they walk further into wrong. This is correction as kindness — consequences arriving early enough to teach. Take your own restrictions this way: not as persecution but as the natural result of a misstep, and a cheap lesson if learned now. The first mistake is tuition; only the repeated mistake is a verdict.

Line 2

Biting Through Tender Meat

Biting through tender flesh, so deep the nose disappears. No blame.

The correction is easy — the fault is obvious, the meat tender — yet the bite goes deep, driven by indignation. Excess here is understandable and lightly judged, but it is still excess. When wrong is plain and anger feels righteous, watch the force of your response: justice needs no fury. Remain humble and measured while the correction proceeds; the case being clear does not license the sinking of the whole face into it.

Line 3

Biting on Old Dried Meat

Biting on old dried meat and striking something poisonous. Slight humiliation. No blame.

An old wrong, long-preserved: tough to chew, and toxic inside. Punishing a long-standing grievance — where our own authority or standing is compromised — stirs up hatred and resistance, and we come away with a bitter taste. The counsel is to withdraw from the reactive cycle: revenge on old conflicts feeds a retaliation that never ends. Seek resolution and release rather than retribution; the slight humiliation of letting go is far cheaper than the poison of biting down.

Line 4

Dried Gristly Meat

Biting on dried gristly meat, one receives metal arrows. It is favourable to remember the difficulty and stay steadfast. Good fortune.

The hardest bite of the hexagram — powerful opposition, a genuinely tough case — but this time the fight is right, and the tools are given: arrows of metal, straightness and strength. Progress is being made; the other side begins to respond. Do not relax into old habits and do not harden into brutality: be neither soft nor savage, and keep the difficulty in mind for as long as it lasts. Disciplined persistence through the gristle brings good fortune.

Line 5

Yellow Gold

Biting on dried lean meat, one receives yellow gold. Steadfastly aware of danger. No blame.

The case is clear and the authority to judge is yours — but judge like gold and the middle way: true, impartial, unbending. Do not accept alliances merely because they are offered, and do not shield people from the consequences of what they have done; help only those working to correct themselves. Resist leniency that would reopen the wound, and resist re-entering too soon. Mild in manner, exact in substance, and always vigilant of the danger — so the verdict stands without blame.

Line 6

The Cangue

His neck is locked in the wooden cangue, hiding his ears. Misfortune.

The incorrigible end: deafness itself. The ears disappear beneath the very punishment their refusal to hear has earned — stubbornness that ignored every warning, insisting on its own way until shame closed around the neck. If this is you, the exit is humble and gradual: return to the correct path a step at a time, trusting that the universe can turn even this to good. If it is another, learn the line's plain arithmetic: warnings unheard compound; the first stocks were mercy, the cangue is arrival.

Sage advice

When something stands between what belongs together, bite through — cleanly, justly, and without hatred. Establish clear standards before you enforce anything, act at the right moment with full energy, and stop the instant justice is done. Thunder and lightning together: force and clarity. Force without clarity is violence; clarity without force is complicity. Justice is their union.
