Guilt is identification with past error. By holding onto the errors of the past, there can be no possibility of change in the present. If there exists no possibility of change in the present, then the future is nothing more than a continuation of the past.
Continuity of the past into the future is the ego’s goal. But it is not our goal.
We look within, letting go of guilt and embracing the present moment without judgment. Only this is real. We continue tomorrow and each day after that.
