Hexagram 21 · Biting Through (噬嗑 Shì Kè)
Fire ☲ over Thunder ☳
Jaws with something stuck between them · the bite that frees
Biting Through is the hexagram of decisive correction, of dealing with the obstacle that sits between you and what you want by biting clean through it. The figure even looks like a mouth: solid lines at top and bottom for the lips, and one stubborn solid line in the middle, the thing stuck between the teeth. You cannot chew around it. The book's answer is to bite firmly, to apply justice cleanly, and to remove what is blocking the way.
Fire sits above, clarity and light; Thunder sits below, movement and force. Together they make the energy of a clear-eyed, forceful action, the kind that sees exactly what the obstruction is and deals with it. The commentary connects this to law and discipline, advising that penalties be made clear and boundaries plain. This is the hexagram where gentleness alone would fail and firm, fair correction succeeds, but the firmness is always meant to be just, not cruel.
What this hexagram counsels in a reading
When Shi Ke answers your question, something stubborn is standing in the path, and the counsel is to address it directly and fairly rather than working around it. Apply the necessary discipline without descending into harshness. The hexagram is clear that the blockage must actually be removed; tiptoeing around it only prolongs the problem. At the same time, the bite is meant to be clean and just, a clear correction rather than a punishment driven by anger. Name the obstacle plainly and deal with it.
In love and relationships
For relationships, Biting Through often points to an obstacle or a hard truth that has to be confronted directly, a problem you have both been chewing around without resolving. The counsel is to address it openly and fairly rather than avoiding it. Clear it cleanly. This can mean a difficult but necessary conversation, the kind that removes the thing stuck between you. Done justly and without cruelty, it opens the way to real closeness.
In work and money
In work, Shi Ke favours decisive action to clear a blockage, enforce a standard, or correct a problem that has been festering. Be firm and fair. With money, it can point to settling a dispute, enforcing terms, or cutting through an obstruction that is holding up progress, always with clarity and fairness rather than vindictiveness. The energy is corrective, and it works when it is clean.
Moving lines and the changing hexagram
The moving lines of Biting Through use the imagery of biting into tough, sometimes dried, meat and occasionally hitting metal or poison, describing the difficulty and the care that correction requires. A changing line here usually comments on how cleanly and justly the obstacle is being dealt with, and how much resistance it offers. Read it as guidance on applying firm correction fairly. The hexagram it becomes shows what opens up once the blockage is bitten through.
Its Tarot kin
On the deck side of this site, Biting Through rhymes with Justice. Both are about clear, fair correction, applying judgment cleanly to set a situation right. Justice weighs the matter and acts without malice; Shi Ke is that same decisive fairness, the firm bite that removes what blocks the way.
