Hexagram Twenty-One

Biting Through
Thunder and lightning together: the decisive bite through an obstruction.


An obstacle sits between the jaws, and the counsel is to bite cleanly through it. This hexagram concerns obstructions that do not dissolve on their own — an unresolved matter, an unaddressed unfairness, a knot everyone walks around. Energetic clarity, applied once and lawfully, restores the flow that politeness could not. Its counsel is proportionate firmness: name the issue exactly, act decisively, and let the penalty fit the case precisely.
On wealth
Address the specific blockage — the unpaid item, the unclear term — directly and formally, then move on.
