If 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.
ZhuangziStudy is to study what cannot be studied. Undertaking means undertaking what cannot be undertaken. Philosophizing is to philosophize about what cannot be philosophized about. Knowing that knowing is unknowable is true perfection.
ZhuangziGoods and possessions are no gain in his eyes. He stays far from wealth and honor. Long life is no ground for joy, nor early death for sorrow. Success is not for him to be pround of, failure is no shame. Had he all the world's power he would not hold it as his own. If he conquered everything he would not take it to himself. His glory is in knowing that all things come together in One and life and death are equal.
