In a river mist, if another boat knocks against yours, you might yell at the other fellow to stay clear. But if you notice then, that it's an empty boat, adrift with nobody aboard, you stop yelling. When you discover that all the others are drifting boats, there's no one to yell at. And when you find out you are an empty boat, there's no one to yell.
ZhuangziListening stops with the ears, the mind stops with recognition, but spirit is empty and waits on all things.
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.
ZhuangziAn archer competing for a clay vessel shoots effortlessly, his or her skill and concentration unimpeded. If the prize is changed to a brass ornament, the hands begin to shake. If it is changed to gold, he or she squints as if going blind. The abilities do not deteriorate, but belief in them does, as he or she allows the supposed value of an external reward to cloud the vision.
