Srimad Bhagavatam 10.14.8
Forgiveness doesn’t mean you have to make a wrong a right. It means you release yourself from the resentment you feel towards the offender. Is that a lot to ask? Yes. But otherwise the resentment you maintain will continue to harm you, not only spiritually, but emotionally and physically. Ultimately, we practice forgiveness because we value our spiritual connection more than we desire to see our enemy punished.
