The things that have acquired unity are these: Heaven by unity has become clear; Earth by unity has become steady; The Spirit by unity has become spiritual; The Valley by unity has become full; All things by unity have come into existence.
LaoziTo know people is wisdom, but to know yourself is enlightenment. to master people takes force, but to master yourself takes strength. to know contentment is wealth, and to live with strength resolve. to never leave whatever you are is to abide, and to die without getting lost- that is to live on and on.
Laozi
