In I we see the upper trigram diminished, and the lower added to. The satisfaction of the people, in consequence, is without limit. What descends from above reaches to all below, so great and brilliant is the course of its operation.

That 'it will be advantageous even to cross the great stream', appears from the action of wood, shown in the upper trigram.
I is made up of the trigrams of movement and penetrating mildness, through which there is daily advancement to an unlimited extent. We have the idea of heaven dispensing and earth producing, leading to an increase without restriction of place. Everything in the method of this increase proceeds according to the requirements of the time.
