Nine in the fifth place means

Contemplation of my life.

The superior man is without blame.

A man in an authoritative position to whom others look up must always be ready for self-examination. The right sort of self-examination, however, consists not in idle brooding over oneself but in examining the effects one produces. Only when these effects are good, and when one's influence on others is good, will the contemplation of one's own life bring the satisfaction of knowing oneself to be free of mistakes.
