Forgiveness is a brave man's act, it needs a lot of guts to let go the anger and hatred. Forgiveness is the key to a happy life. If you do not forgive a person for the mistakes they have committed or the damage they have caused to you, it will be you who will be caught in this feeling of hatred, resentment or revenge. "I forgive not because I become a Saint, But because I am tired of Hating"
Once a person asked 'What is forgiveness?' The Sufi replied ' Its the fragrance that flowers give when they are crushed.'
