Hexagram 21: Biting Through (Shi He)
Hexagram 21, Biting Through, is about removing an obstacle that blocks communication or progress. It suggests that a clear, fair decision, stated firmly and acted on without delay, can open a path that has been stuck. It also reminds you that lasting resolution comes from addressing the actual cause rather than only the surface.

What does hexagram 21 mean?
The traditional text says that this is a time when pressing forward on a matter brings benefit, and that it helps to bring the issue into the open before the proper authority. It describes an obstruction that must be bitten through, like a hard morsel caught between the teeth, before nourishment can pass. In your own words, the message is that progress often needs a clean break through the blockage rather than patient waiting. Reflect on whether the thing in your way is something you can genuinely clear.
The image
Fire above thunder pictures lightning, which is bright and sharp and strikes with sudden force. The ancient rulers were said to use this combination to make penalties clear and laws firm, so that people understood the rules and their consequences. The lesson for you is to be direct and fair, letting clarity and firmness work together so that obstacles are dealt with openly.
Biting Through in love
In relationships, this hexagram invites an honest conversation about a sore point that has been left unspoken. Naming the disagreement plainly, and listening with the same clarity, can clear the air and bring you closer. The challenge is to be firm without being harsh, since sharpness delivered carelessly can wound rather than resolve.
Biting Through for work and money
At work, this theme suits situations where a stalled project, unclear responsibility, or tangled process needs a decisive fix. Setting clear terms, asking the right person to decide, and following through can release momentum that has been held back. Be wary of rushing into conflict, because a fair, well-documented approach usually earns more trust than force.
Changing lines
When a line in this hexagram changes, the reading often points to the nature of the obstacle, such as whether it is minor and easily cleared or stubborn and in need of stronger action. Changing lines are best read as a prompt to examine how you are biting through the problem, not as a fixed outcome.
Advice
Identify the one obstacle that matters most and address it directly, fairly, and soon. Pair your firmness with a clear explanation so others can see the reasoning behind your decision.
