When someone harms you, see that person as a kind teacher showing you the path to liberation. Pray that you may be able to help that person and never hope for revenge.
Look right into it, and you will see that the person who is harmed, the person who does the harm, and the harm itself are all totally devoid of any inherent reality. Faced with these empty appearances, is there anything to be lost or gained? It is all like an empty sky. Recognize that!
As long as you pay heed to your hatred and attempt to overcome your external opponents, even if you succeed, more will inevitably rise up in their place. Even if you managed to overpower everyone your anger would only grow stronger. The only really intolerable enemy is hatred itself. To defeat the enemy of hatred, meditate one-pointedly on patience and love until they truly take root in your being. ~ Dilgo Khyentse Rinpoche
