The Image
Wind and thunder; these form I. The superior man, in accordance with this, when he sees what is good, moves towards it; and when he sees his errors, turns from them.

Miscellaneous Signs
How fulness and decay their course begin, is seen in Sun, in I again.

The Judgement
I indicates that in the state which it denotes, there will be advantage in every movement which shall be undertaken, that it will be advantageous even to cross the great stream.

Appended Judgement
In I we see richness of virtue, and abundance of growth without any contrivance. I appears in promoting the advantageous.

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 'there will be advantage in every movement which shall be undertaken', appears from the central and correct positions of the second and fifth line, and the general blessing, the dispersion of which they imply. 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.

The Lines and commentaries
Bottom nine
Showing that it will be advantageous for its subject in his position to make a great movement. If it be greatly fortunate, no blame will be imputed to him.
'If the movement be greatly fortunate, no blame will be imputed to him': it is not for one in so low a position to have to do with great affairs.
Six in the second place
We see parties adding to the stores of its subject ten pairs of tortoise shells whose oracles cannot be opposed. Let him persevere in being firm and correct, and there will be good fortune. Let the king, having the virtues thus distinguished, employ them in presenting his offerings to God, and there will be good fortune.
'Parties add to his stores': they come from beyond his immediate circle to do so.
Six in the third place
Showing increase given to its subject by means of what is evil, so that if he shall be led to good, he shall be without blame. Let him be sincere and pursue the path of the mean; so shall he secure the recognition of his ruler, like an officer who announces himself to his prince by the symbol of his rank.
'Increase is given by means of what is evil and difficult': as he has in himself these qualities called forth.
Six in the fourth place
Showing its subject pursuing the due course. His advice to his prince is followed. He can with advantage be relied on in such a movement as that of relocating the capital.
'His advice to his prince is followed': his only object in it being the increase of the general good.
Nine in the fifth place
Showing its subject with sincere heart seeking to benefit all below. There need be no question about it: the result will be great good fortune. All below will with sincere heart acknowledge his goodness.
'The ruler with sincere heart seeks to benefit all below': there need be no question about the result.
'All below with sincere heart acknowledge his goodness': he gets what he desires on a great scale.

Top-most nine
We see one to whose increase none will contribute, while many will seek to assail him. He observes no regular rule in his heart. There will be evil!
To his increase none will contribute': this expresses but half the result.
'Many will seek to assail him': they will come from beyond his immediate circle to do so.
