Buddhist Prayer of Forgiveness - If I have harmed anyone in any way, I ask their forgiveness. If anyone has harmed me in any way, I forgive them. And if I am not ready to forgive, I forgive myself for that.
When you look deeply into your anger, you will see that the person you call your enemy is also suffering. As soon as you see that, the capacity for accepting and having compassion for them is there. - Thich Nhat Hanh this
