言有宗，事有君。夫唯無知，是以不我知。
There is an originating and all-comprehending (principle) in my words, and an authoritative law for the things (which I enforce).
It is because they do not know these, that men do not know me.
知我者希，則我者貴。
They who know me are few, and I am on that account (the more) to be prized.
是以聖人被褐懷玉。
It is thus that the sage wears (a poor garb of) hair cloth, while he carries his (signet of) jade in his bosom.
