Why forgive?

For some odd reason, I cannot remembner many ways people have wronged me. I know they have, but I do not remember, neither do I try. In what I've learned of psychology, forgiveness is often a key element in solving psychological dilemmas (your nervous disorders, illogical hangups, unreasonableness, attitude problems). Forgive yourself, forgive those who have wronmged you, even those who do not see they have hurt you. That way, you can move on without anger poisoning your life, seeping deep into your heart and mind, and spoiling many a moment of joy and peace. It is my theory that looking at all the mistakes you have made from others eyes can help. Looking at the situation through the eyes of the offender may also help. "Forgive my transgressions as I forgive those who transgress against me."
