Biting Through, Line 4

The fourth line gives Biting Through its hardest mouthful and its best reward. Legge's translation describes gnawing flesh dried on the bone and obtaining the pledges of metal and arrows, and counsels that it will be advantageous to recognise the difficulty of the task and remain firm, in which case there is good fortune. The obstruction here is the most stubborn in the hexagram, meat that has dried onto bone and will not separate, and what is recovered from it is not soft matter at all but something straight and hard.

The arrow supplies the sense of the reward. An arrow is straight, and metal does not bend under pressure, so the pledge taken out of the difficulty is a commitment that will hold. Nothing about this line suggests the work is quick. Its promise is that the work is worth doing, which is a different promise from the effortless bite of the second line, and a better one.

This yang stroke opens the upper trigram Li, fire and clarity, from an even position that classical commentary treats as incorrect for a firm line. The mismatch is why the text adds its condition rather than simply promising good fortune. Strength placed where yielding is expected can force a matter and lose it; the instruction to recognise the difficulty first is what keeps that strength deliberate. Good fortune here is earned by naming the size of the task before starting, and then not letting go of it.

This changing line answers a querent facing an obstruction that will not yield to ordinary effort, and its counsel is unusually procedural. Before pressing on, state honestly how hard the thing actually is. The text makes advantage conditional on exactly that recognition, and the reason is practical rather than moral: a task undertaken with the wrong estimate of its size gets abandoned partway, at the worst possible moment, when the cost has been paid and the reward has not yet been reached.

What the line promises in return is solid. Metal and arrows are pledges that hold their shape, so the outcome of persistence here is a durable commitment, a settled agreement, or a resolution that will not need reopening. Readings landing on this line often concern negotiations that have gone on too long, entrenched institutional problems, or a relationship difficulty that everyone has been working around rather than through.

The stroke is yang in an even place at the base of the upper trigram Li, firmness where yielding is formally expected, which is where the risk lives. A querent with real force available may be tempted to apply all of it at once and break what should have been separated patiently. Firmness in this line means duration rather than intensity. Sustained pressure with a clear view of the difficulty produces the good fortune promised; a single hard push, made without measuring the task, produces the wasted effort the line is written to prevent.
