Introduction
Thunder and lightning together: force with light on it. Biting Through pictures chewing through something hard to make the way clear.
In practice, this names a stretch where one obstacle has to be dealt with. Naming it plainly is most of the work.
The judgement
“Biting Through has success. It furthers one to let justice be administered.”
In plain words: dealing with the obstruction works here, and a fair process is what makes it clean.
Read it as a note about method. The bite has to be firm enough to break through and fair enough to hold afterwards.
Core themes
- One obstacle stands in the way. Find the exact one.
- Firmness works here. Avoidance does not.
- Handle it fairly, or it comes back in a worse shape.
Line-by-line overview
Six lines, read bottom to top — matching the figure above.
Each line describes one stage in an evolving situation. Line 1 marks the earliest, foundational beginning; line 6 shows where the pattern has run its course. Open a line to read it.
Line 1 初九
At the base, movement is blocked from the start, and the old line finds no fault in it.
A stop at this stage prevents a larger problem later.
Being halted early is cheaper than being halted late.
Line 2 六二
Here the obstacle is soft, and the bite goes deeper than it needs to.
The old image is a bite so deep that the nose vanishes.
Ease does that.
Line 3 六三
At this level the obstruction is stale, and biting into it is unpleasant.
The old line allows a small humiliation and no great fault.
Old problems rarely open cleanly.
Line 4 九四
Here the obstacle is genuinely hard, and this line has the tools for it.
The old image is receiving metal arrows: something made for difficult work.
Persistence through the difficult bite is what this line asks for.
Line 5 六五
At the centre, the bite lands and the result is valuable.
The old line adds that the danger is kept in view throughout.
Success here does not remove the need for care.
Line 6 上九
At the top, the obstruction has closed around the whole person.
The old image is a wooden collar that hides the ears: no warning gets through.
Ignoring early stops tends to produce this line.
Summary
Read as a whole, this figure asks you to bite through one real obstacle. Name it exactly, act firmly, keep the handling fair, and do not wait until it closes around you.

Hexagram 21 · Biting Through 噬嗑
A way to look at what is moving around you now, not a fixed answer. Notice your inner state, then decide how to act.
One specific thing stands between you. Name it rather than circling it.
A direct conversation tends to clear more than several careful hints.
People often soften the issue until it becomes unrecognisable. Softening tends to keep it.
Be fair while you are direct. Fairness is what lets the bond stay open afterwards.
Ultimately, your real-world facts and personal choices will shape how things unfold.

- Ask how firm you actually need to be. Too little force leaves the blockage in place, and too much tends to leave damage of its own.
