Independent inquiry is needed in your search for truth, not dependence on anyone else's view or a mere book.
Bruce LeeLet the spirit out - Discard all thoughts of reward, all hopes of praise and fears of blame, all awareness of one's bodily self. And, finally closing the avenues of sense perception, let the spirit out, as it will.
Bruce LeeForget about winning and losing; forget about pride and pain. Let your opponent graze your skin and you smash into his flesh; let him smash into your flesh and you fracture his bones; let him fracture your bones and you take his life! Do not be concerned with escaping safely- lay your life before him!!
Bruce Lee
