Imagine you are crossing a river in a boat. Suddenly, an empty boat hits yours. Even if you are in a bad mood, you will not become very angry at an empty boat.
Now imagine that a man is in the boat that hit you. You will shout, “Hey, watch out!”
If the man doesn’t respond, you will shout louder. All because there is someone in the boat.
Empty boat, no anger.
Person in the boat, anger.
Now, what if you empty your own boat as you cross the river of the world? Then, no one will oppose you; no one will seek to harm you. You will feel no anger.
Empty your boat.
