Six at the top means:

He meets with firm allegiance
And is still further bound.
The king introduces him
To the Western Mountain.


This refers to a man, an exalted sage, who has already put the turmoil of the world behind him. But a follower appears who understands him and is not to be put off. So the sage comes back into the world and aids the other in his work. Thus there develops an eternal tie between the two. The allegory is chosen from the annals of the Chou dynasty. The rulers of this dynasty honored men who had served them well by awarding them a place in the royal family's temple of ancestors on the Western Mountain. In this way they were regarded as sharing in the destiny of the ruling family.
