Turning inwardly (self-cultivation, of mind, body and spirit), the sage comes to know the outside as part of all the parts of being (the Tao). Striving outwardly (without regard for self-cultivation), the driven man lives beyond his needs, and with his desires perpetually unsatisfied. Coming to know a thing means coming to be part of the thing. Covetting a thing keeps it always beyond one's grasp. The mind needs a light touch. The body needs unbroken endurance, and the spirit needs to know the heart. "
