The weak can never forgive. Forgiveness is the attribute of the strong.
The worldly people may forgive their adversaries, but the saints not only forgive but also work for their redemption.
Nirankari Baba Hardev Singh Ji (Book : Gems of Truth)
To forgive is the highest, most beautiful form of love. In return, you will receive untold peace and happiness.
Let us forgive each other – only then will we live in peace.
Leo Nikolaevich Tolstoy
Forgiveness does not change the past, but it does enlarge the future.
