Zhuangzi

 If a man crosses a river

and an empty boat collides with his own skiff,
Even though he be bad tempered man
He will not become very angry.
But if h

e sees a man in the boat,
He will shout at him to steer clear.
If the shout is not heard, he will shout again, and yet again, and begin cursing.
And all because someone is in the boat.
Yet if the boat were empty,
He would not be shouting, and not angry.
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"
