The Judgement:
Lü suggests the idea of one treading on the tail of a tiger, that does not bite him.
There will be progress and success.

Appended Judgement:
Lü shows us the foundation of virtue and the perfection of harmony.
Lü also appears in the harmony of conduct.
See also Ta Chuan, section II, chapter VII, §§ 2-4.

Commentary:
In Lü we see weakness (the yin-line) treading on strength. The lower trigram indicates pleasure and satisfaction, and responds to the upper, representing strength. Hence 'he treads on the tail of a tiger, that does not bite him; there will be progress and success'.
The fifth line is strong , in the centre, and in its correct place. Its subject occupies the God-given position, and falls into no distress or failure; his actions will be brilliant.

The Lines:

Nine in the bottom place:
This line shows its subject treading his accustomed path. If he go forward, there will be no error.
____________________________________
Nine in the second place:
Showing its subject treading a path that is level and easy; a quiet and solitary man, to whom, if he be firm and correct, there will be good fortune.
____________________________________
Six in the third place:
 X
A one-eyed man who thinks he can see well; a lame man who thinks he can walk; one who treads on the tail of a tiger and is bitten. All this indicates ill fortune. We have one merely acting the part of a great ruler.
____________________________________
Nine in the fourth place:
Showing its subject treading on the tail of a tiger. He becomes full of apprehensive caution; in the end there will be good fortune.
____________________________________
Nine in the fifth place:
 O
Showing the resolute tread of its subject. But though he be firm and correct, there will be peril.
____________________________________
Top-most nine:
This line suggests to look at the whole course that is trodden, and examine the signs encountered. If they be complete and without failure, there will be great good fortune.

Commentaries:

Nine in the bottom place:
'He treads his accustomed path and goes forward': singly and exclusively he carries out his wishes.
____________________________________
Nine in the second place:
'A quiet and solitary man, to whom, being firm and correct, there will be good fortune': holding the due mean, he will not allow himself to be thrown into disorder.
____________________________________
Six in the third place:
'A one-eyed man who thinks he can see': he is not fit to see clearly.
'A lame man who thinks he can walk': one cannot walk along with him.
The 'ill fortune of being bitten', arises from the place not being the proper one for him.
'One merely acting the part of a great ruler': this is owing to his aims being too violent.
____________________________________
Nine in the fourth place:
'He becomes full of apprehensive caution; in the end there will be good fortune': his aim takes effect.
____________________________________
Nine in the fifth place:
'He treads resolutely; but though he be firm and correct, there will be peril': he treads resolutely, due to his being in the position that is correct and appropriate to him.
____________________________________
Top-most nine:
'There will be great good fortune', and that in the occupancy of the top-most line: this is great matter for congratulation.
