Understanding others is knowledge, Understanding oneself is enlightenment; Conquering others is power, Conquering oneself is strength.
LaoziIf you overesteem great men, people become powerless. If you overvalue possessions, people begin to steal. The Master leads by emptying people's minds and filling their cores, by weakening their ambition and toughening their resolve. He helps people lose everything they know, everything they desire, and creates confusion in those who think that they know. Practice not-doing, and everything will fall into place.
Laozi
