The past is the past. It has no foothold in us save for the parts of us that are fascinated with reliving the pain for the purpose of confirming the reality of self.
The darkness that torments us over what we may have done does so to keep its place in us now. By misdirecting our attention to a time now passed, it’s able to “hide” in us the present.
Refuse to relive what was… instead, agree to see yourself as you are now. This is the only way for us to die to what lives within us at our expense. Yes, it’s painful, but “evil” isn’t an act; in some ways it’s in the part of us that clings to what was in order to “be” now.
