Nine in the fifth place describes command that no longer has to be used. The king reaches his family, there is nothing to be anxious about, and the outcome is good. A querent drawing it usually holds responsibility over people who are close to them, and the reading concerns the difference between running such an arrangement and simply being trusted inside it.
The counsel is to stop working the position. Anxiety is what the line explicitly removes, and it removes it before promising anything, which puts the order of operations on record: the situation improves once the person at its head stops managing it as though it might fail at any moment. That is a hard instruction for anybody who arrived at the fifth line by way of the third, where severity was the instrument, and it is aimed at precisely that reader.
When the line changes, the upper trigram Xun becomes Gen and the figure becomes Grace, King Wen 22, the classic's study of form and adornment, fire lighting a mountain from below. Read from the ruling line of The Family, the transformation is a fair warning as well as a compliment. Authority that no longer needs to act begins to consist largely of how it appears, and Grace is unusually honest about how much a fine surface can carry and about the point past which it is carrying nothing at all.
