" In a cruel irony, a refusal to forgive works its negative energy most powerfully in the wronged party. Archbishop Desmond Tutu2, a master of forgiveness, describes the process: To forgive is not just to be altruistic; in my view it is the best form of self-interest. The process of forgiving does not exclude hatred and anger. These emotions are all part of being human. When I talk of forgiveness I mean the ability to let go of the right to revenge and to slip the chains of rage that bind you to the person who harmed you. When you forgive you are free of the hatred and anger that locks you in a state of victimhood. If you can find it in yourself to forgive, you can move on, and you may even help the perpetrator to become a better person. "
