Perhaps it's possible to forgive in one grand swoop, but I didn't experience it that way. I did it in bits and pieces. You forgive what you can, when you can. To forgive does not mean overlooking the offense and pretending it never happened. Forgiveness means releasing our rage and our need to retaliate, no longer dwelling on the offense, the offender, and the suffering, and rising to a higher love. It is an act of letting go so that we can go on.
When somebody you've wronged forgives you, you're spared the dull and self-diminishing throb of a guilty conscience. When you forgive somebody who has wronged you, you're spared the dismal corrosion of bitterness and wounded pride. For both parties, forgiveness means the freedom again to be at peace inside their own skins and to be glad in each others' presence.
