Remembering is the alter-ego of forgetting. Forgiveness’s elemental power is freeing you to know “what YOU are,” but that can’t happen if you hang on to things that take you from it, e.g., all that you remember.
Sure, you can move on, but without forgetting, the anchor of remembering grows more massive, and the power of forgiveness fades under the weight. The loss is only yours, and it is an enormous loss. Forgive and forget; if you don’t, you’ll never “remember” YOU!
