The Judgement:
I indicates that with firm correctness, there will be good fortune in what is denoted by it.
We must look at what we are seeking to nourish, and by the exercise of our thoughts seek for the proper nourishment.

Commentary:
'I indicates that with firm correctness, there will be good fortune': that is, when the nourishing is correct.
'We must look at what we are seeking to nourish': we must look at whom we are seeking to nourish.
'We must by the exercise of our thoughts seek for the proper nourishment': we must look to our own nourishing of ourselves.
Heaven and earth nourish all things. The sages nourish men of talents and virtue, by them to reach to the myriads of people. Great is the work intended by this nourishing in its time!

The Lines:

Nine in the bottom place:
The first nine seems to be thus addressed: 'You leave your efficacious tortoise, and look at me till your lower jaw hangs down'. There will be evil.
____________________________________
Six in the second place:
Showing one looking downwards for nourishment, which is contrary to what is proper; or seeking it from the height above, advance towards which will lead to evil.
____________________________________
Six in the third place:
Showing one acting contrary to the method of nourishing. However firm he may be, there will be evil. For ten years let him not take any action: it will not in any way be advantageous.
____________________________________
Six in the fourth place:
Showing one looking upwards for the power to nourish. There will be good fortune.
Looking with a tiger's unwavering glare, and with his desire that impels him spring after spring , he will fall into no error.
____________________________________
Six in the fifth place:
 O
One acting contrary to what is proper; but if he abide in firmness, there will be good fortune. He should not, however, try to cross the great stream.
____________________________________
Top-most nine:
 O
Showing him from whom comes the nourishing. His position is perilous, but there will be good fortune.
It will be advantageous to cross the great stream.

Commentaries:

Nine in the bottom place:
'You look at me till your lower jaw hangs down': the subject of the line is thus shown unfit to be thought noble.
____________________________________
Six in the second place:
The 'evil of advance by the subject' shown here, is owing to his leaving in his movements his proper associates.
____________________________________
Six in the third place:
'For ten years let him not take any action': his course is greatly opposed to what is right.
____________________________________
Six in the fourth place:
The 'good fortune attached to looking upwards for the power to nourish', shows how brilliant will be the diffusion of that power from the subject of the top-most line.
____________________________________
Six in the fifth place:
The 'good fortune from abiding in firmness', is due to the docility of the line's subject in following the subject of the top-most line.
____________________________________
Top-most nine:
The 'good fortune, notwithstanding the peril of his position, of him from whom the nourishing comes', affords great cause for congratulation.
