Forgiveness is very liberating, especially to the one who forgives. Anger and thoughts of revenge can really get in your way. When you forgive the person you are angry with, the greatest freedom you generate is your own. Once you see that the person you are so immensely angry with is just a wounded soul like you, forgiving them is all the easier.
