Psychological forgiveness requires regret on the part of the offender, amends, and the ceasing of the harmful action. The event loses any significance, any grief, and is forgotten. Maybe, some right learning has occurred, but life moves on.
Divine forgiveness asks for none of those things. It is a merciful act. And, it always includes a karmic lesson. With this interconnectedness of all things revealed, both perpetrator and victim receive grace. Divinity is approached, with more love, light, and truth in relationship.
