"Anger is like a storm rising up from the bottom of your consciousness. When you feel it coming, turn your focus to your breath. Breathe in deeply to bring your mind home to your body. Then look at, or think of, the person triggering this emotion: With mindfulness, you can see that he is unhappy, that he is suffering. You can see her wrong perceptions. You can see that he is not beautiful when he says things that are unkind. You can also see that you don't want to be like him. You'll feel motivated by a desire to say or do something nice -- to help the other person suffer less. This means compassionate energy has been born in your heart. And when compassion appears, anger is deleted."
There is a saying in Hebrew - אין אדם רע - יש אדם שרע לו
There are no evil people - just people for whom life is "evil" [i.e. difficult]. I don't believe that this is fully true. There are evil people. But most of the people with whom we come into contact are not - they are just having a rough time. Remember that, feel compassion - and anger gone.
