Tao is the source of both fullness and emptiness. But it is itself neither fullness nor emptiness.
ZhuangziOnce I dreamed I was a butterfly, and now I no longer know whether I am Chuang Tzu, who dreamed I was a butterfly, or whether I am a butterfly dreaming that I am Chuang Tzu.
ZhuangziCan a man cling to the positive without any negative in contrast to which it is seen to be positive? If he claims to do so he is a rouge or a madman.
ZhuangziOnly the intelligent knows how to identify all things as one. . . . When one is at ease with himself, one is near Tao. This is to let Nature take its own course.
ZhuangziPeople value that part of knowledge which is known. They do not know how to avail themselves of the Unknown in order to reach knowledge. Is this not misguided?
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.
