When you feel you are being harmed by someone

When you feel you are being harmed by someone, remember that the harm that person may be inflicting on you (or someone dear to you) is the direct result of yourself having harmed others in the past. Reflect that this person is so overpowered by delusion that he or she is as if possessed, and cannot resist harming you. As a result of this harm, he or she will have to suffer in samsara’s lower realms in a future life. When you think how terrible that will be, you will feel only sadness and pity rather than anger. ~ Kyabje Dilgo Khyentse Rinpoche
