When an archer is shooting for nothing, he has all his skill. If he shoots for a brass buckle, he is already nervous. If he shoots for a prize of gold, he goes blind or sees two targets - He is out of his mind! His skill has not changed. But the prize divides him. He cares. He thinks more of winning than of shooting- And the need to win drains him of power.
ZhuangziBut you now, you wear your soul on your sleeve, exhausting your energy, propping yourself up on a tree, mumbling, or bent over your desk, asleep. Heaven gives you a form and you wear it out by pointless argument.
ZhuangziIf a man is crossing the river and an empty boat collides with his skiff, even though he is a bad tempered man he will not become very angry. But if he sees a man in the other boat he will scream and shout and curse at the man to steer clear. If you can empty your own boat crossing the river of the world, no one will oppose you, no one will seek to harm you. Thus is the perfect man - his boat is empty.
