Source reading and stance
Core image
This hexagram shows a blockage that cannot stay where it is. Something sits between the teeth of the system: a disturbance, a transgression, a hard piece that obstructs the flow. What is needed here is not softness first, but decisive setting-right. What closes the passage must be seized.
Tension
Biting through is dangerous work, because correction can quickly turn into hardness. Yet too much softness is just as wrong here. The situation asks for a sharpness that does not grow cruel, and for a penalty that does not enjoy itself. Doing justice here is something other than acting out your drive.
Distortion
Biting through distorts when one either hesitates until the damage grows, or identifies too eagerly with the sanction. Then the correction is either too slack or too heavy. In both cases the passage stays damaged.
Stance
Seize exactly what blocks the passage, no more and no less. Let the correction be clear and free of theater. What is set right here must restore the flow, not only assign blame. A good bite breaks the hard piece, not the whole mouth.
Closing line
Whoever does not dare to correct often, unnoticed, chooses longer decay.

Changing lines of hexagram 21
- Line 1. At the start the disturbance is still small enough for light correction. That is favorable. What is set right early need not be tackled heavily.
- Line 2. Here the bite grows firmer. The obstacle already sits deeper and asks for more force. Yet measure can still be kept.
- Line 3. At this point the correction chafes against something difficult and stubborn. That breeds irritation and the risk of excess. This line asks for perseverance without a hardening of heart.
- Line 4. Here a hard piece is finally truly gripped. It costs effort, but it is right. The passage only begins to heal when one stops working around the obstacle.
- Line 5. This line corrects from central measure. The hardness here is not blind, but justified. Because of that the sanction can bear weight without becoming contaminated.
- Line 6. When correction comes too late, the rigidity grows so great that the repair too turns out hard. Then there is less room for nuance. This line is a warning against prolonged neglect.
