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.
Through intuitions received in the silence and holiness of your own inner sanctuary, you will get the guiding Light you need in your work.
