Legge's translation of the topmost line reads that the topmost nine, undivided, shows how the rain has fallen and the onward progress is stayed, so that the full accumulation of virtue represented by the upper trigram must now be valued, though a wife, however firm and correct, is in a position of peril in maintaining such restraint. The commentary notes only that the rain has fallen and the movement is stayed because the power denoted in the figure has accumulated to its full measure.
Nine at the top closes Xun, the upper trigram, at its highest place, and it marks the point at which the small, gentle restraint that has run through the whole hexagram finally reaches completion. The Judgment's own image of dense clouds gathering from the west without yet releasing rain is answered here at last, the rain falls, meaning the accumulated force has finally been released rather than merely gathered.
Yet Legge's text adds a caution rather than simple triumph, since firmness that continues to insist on restraint after the restraining work is already done risks becoming its own kind of danger.
The image also closes the hexagram's language of accumulation begun in the Judgment, dense clouds gathering from the west, so that this final line answers the opening figure directly, cloud become rain, restraint become release.
