That knowledge which stops at what it does not know, is the highest knowledge.

Only the intelligent knows how to identify all things as one. . . . When one is at ease with himself, one is near Tao. This is to let Nature take its own course.

Although things seem to be sometimes going up and sometimes descending, sometimes slipping away, nevertheless there is a reality, the same today as in the past. It does not change, for nothing can affect it. Could we not say it is one great harmony? So why shouldn't we ask about it.

All men know the use of the useful, but nobody knows the use of the useless. Where can I find a man who has forgotten words so that I can have a word with him?

The raven hatches its young; the fish spew forth their eggs; the slim-waisted wasp transforms, and when a younger brother comes along the elder brother weeps. For too long I have not been able to work in harmony with these changes. So, given that I did not play my part in harmony with others, how could I expect to change people?

Therefore, the truly great man, although he does not injure others, does not credit himself with charity and mercy (these are natural to him). He does not seek gain, but does not despise his followers who do. He struggles not for wealth, but does not take credit for leaving it alone... The ranks and emoluments of the world are to him no cause for joy, it's punishments and shame no cause for disgrace.

The perfect man of old looked after himself first before looking to help others.
