Nine at the top gives the strongest reading in Nourishment, and it gives it to a querent who is carrying other people. The line describes the position from which the nourishing of others proceeds, states that the position involves peril, and then promises good fortune along with advantage in crossing the great stream. Read as a changing line, it tells somebody who has become the source that a large undertaking is now open to them, on the condition that the danger of their position stays in view rather than being forgotten in the confidence of success.
The reversal from the fifth line is deliberate and instructive. The line below was told not to cross the great stream, because what it distributes is drawn from elsewhere. This line is told to cross, because what it stakes is its own. A querent who has spent a long period supporting others out of resources they genuinely generated is being told that the same resources will bear an ambitious venture, which the hexagram's earlier lines uniformly withhold.
When the line changes, the upper trigram Gen becomes Kun and the figure becomes Return, King Wen 24, the single strong stroke reappearing at the bottom after a period of decline. Read against a line standing at the summit of provision, that destination is a reminder rather than a threat. What is given from the top comes back as a beginning at the bottom, and the peril the text names is what keeps the cycle from ever being taken for granted.
