Forgiveness is the misguided premise that people have the capacity to make individual, independent choices. Evolution is on auto-pilot. If there were such thing as isolated agency (beyond the organizational will of the field of all existence) the result would be unmanageable, runaway chaos.
Therefore there’s nothing and no-one to blame or forgive. This is the whole of the self-regulating cosmic organism—itself doing it to itself.
Be a little patient out there and flow with it. You are not in control of anything.
The art of forgiveness is a form of self love and self interest. Letting go of the past relieves the anxiety and imagination that the past is driving the present. Such clinging is the root of anxiety. One can stop at any time, but this is what makes the game interesting.
