Hexagram 21 of 64 · King Wen sequence
噬嗑 · shì kè
Fire above thunder: something solid stuck between the teeth — an obstruction that must be bitten through before the whole can function.
Mouth open, something hard in the middle: everything works except the one bite. Biting Through is the hexagram of the obstruction — the clause, the habit, the person, the fear that sits between two workable halves and jams the system.
The counsel is about the bite itself: obstructions are removed by a decisive act, applied where it actually sits, with the force the obstruction deserves — nothing more. Public justice was the old remedy; clear consequences, calmly applied, is the modern one.
