Answer of Lama Ole :
If you don’t have any anger in yourself, then you won’t feel any anger outside! I promise you: it is a question of ring and hook. If there is no ring for the hook of your anger to catch, then you see the supposed opponent as a strange animal in a zoological garden performing somersaults. No angry feeling can arise; you only think, “Strange, why does he act in such a funny way?”
By meditating and removing anger in yourself, you become like a duck: everything poured onto you streams down on all sides and you don’t get wet. This is what we are aiming for.
You might cover the whole world outside with leather to walk in comfort. This would be nice, but also a lot of work. Or instead you meditate, which is like putting on shoes. Then you have your own small piece of leather to walk on, and it also doesn’t hurt.
