The Judgement:
Sui indicates that, under its conditions, there will be great progress and success. But it will be advantageous to be firm and correct.
There will then be no error.
See also: Ta Chuan, section II, chapter II, §7.

Commentary:
In Sui we see the strong trigram come and place itself under the weak; we see in the two the attributes of movement and pleasure: this gives Sui.
'There will be great progress and success; and through firm correctness no error': all under heaven will be found following at such a time.
Great indeed are the time and significance indicated in Sui.

The Lines:

Nine in the bottom place:
 O
Showing its subject changing the object of his pursuit; if he be firm and correct, there will be good fortune. Going beyond his own gate to find associates, he will achieve merit.
____________________________________
Six in the second place:
Showing its subject cleaving to the little boy and letting go the man of age and experience.
____________________________________
Six in the third place:
Showing its subject cleaving to the man of age and experience and letting go the little boy.
Such following will get what it seeks; but it will be advantageous to adhere to what is firm and correct.
____________________________________
Nine in the fourth place:
Showing its subject being followed and obtaining adherents. Though he be firm and correct, there will be evil. If he be sincere, however, in his course, and make that evident, into what error will he fall?
____________________________________
Nine in the fifth place:
 O
The ruler is sincere in fostering all that is excellent. There will be good fortune.
____________________________________
Top-most six:
Showing sincerity firmly held and clung to, yes, and binding. We see the king with it, presenting his offerings to the western mountain.
