There are no greater adversaries than yin and yang, because nothing in Heaven or on Earth escapes them. But it is not yin and yang that do this, it is your heart that makes it so.
ZhuangziRight is not right; so is not so. If right were really right it would differ so clearly from not right that there would be no need for argument. If so were really so, it would differ so clearly from not so that there would be no need for 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.
ZhuangziThe true man of the past waited upon Heaven when dealing with people and did not wait upon people when dealing with Heaven.
