“Forgiveness means it finally becomes unimportant that you hit back. You're done. It doesn't necessarily mean that you want to have lunch with the person. If you keep hitting back, you stay trapped in the nightmare…”

1950s, Loving Your Enemies (November 1957)
Context: I think the first reason that we should love our enemies, and I think this was at the very center of Jesus’ thinking, is this: that hate for hate only intensifies the existence of hate and evil in the universe. If I hit you and you hit me and I hit you back and you hit me back and go on, you see, that goes on ad infinitum. It just never ends. Somewhere somebody must have a little sense, and that’s the strong person. The strongperson is the person who can cut off the chain of hate, the chain of evil. And that is the tragedy of hate, that it doesn’t cut it off. It only intensifies the existence of hate and evil in the universe. Somebody must have religion enough and morality enough to cut it off and inject within the very structure of the universe that strong and powerful element of [[love].

"Forgiveness" (7 July 2007)
Context: When you forgive someone, you're not justifying what they've done — you're not saying it was ok, you're letting it go, to stay in the past, where it happened, and moving away from it, so it doesn't sink its teeth into you, and follow you wherever you go. And of course, we don't know what events are going on in that person's life that perhaps led them to do what they were doing, or inspired them, or what kind of person they are sometimes. We never will know everything about what is going on with the whole situation - we only know what has happened to us. And the truth is - there's no point in hanging on to it.
