"I pondered the age-old questions, you know, why does God permit war? Why does God permit injustice? The problem of injustice seemed worse even than the problem of war. I thought about it and thought about it until one day it just hit me, the proverbial flash of inner light in which a solution appeared to me out of the blue. We are all the same person. It was so amazingly simple! There is only one of us. I am you and I am Christ and I am Hitler and I am everybody. There is no injustice in the world. Your suffering is my suffering. The problem of war will end when you realize that in killing me you are only killing yourself."
