Moral Shame and guilt are concerned with the past, they are about something that we have done in the past. We consider the action that we have done in the past using the guidelines of the reflection on "Actions and the Results of Actions". We examine it truthfully, with truthfulness we see that the action or speech that we have done brought Dukkha for ourselves or for others, which brings about Moral Shame.
But to stop it from going into neurotic guilt which kind of freezes us into that moment of time, we have to recognize that we are a changing person, and that we have the opportunity to learn from that particular situation. Then we examine the person who we were in the past; we examine it in this way: What were the views that we had? What hindrances did we have in the mind? Did we have compassion for ourselves at that time? Did we have the understanding, and did we have compassion for the ignorance of the person who we were at that time?
However, we can't just leave it there; we also have to forgive the person that we were and make a determination to try to prevent the same action from arising again in the future. This is quite important; because unless we regret the action, have Moral Shame arise, and make the determination to try to avoid doing it again in the future, we will continue to remain guilty, because we won't bring up the energy to try to avoid it in the present - we won't have learned from it.
So by making a resolution - this is where the Parami of Resolution comes in - we make a resolution to bring forth energy and awareness, compassion and understanding of Cause and Effect to try to prevent it from arising again in the future. This is bringing up effort, this is the sixth factor of the Noble Eightfold Path, and especially the Effort to Prevent. This prevents us from going over and over and over, and feeling guilty and freezing ourselves in the past; we understand that we have the power to prevent it by bringing up compassion for who we are in the present and who we are going to become in the future.
This links Moral Shame to Moral Dread, the fear of having to receive the same sort of Dukkha in the future that we are receiving now from this unpleasant spiritual feeling of understanding our lack of wisdom, or resolve, or mindfulness. Guilt is a type of emotion that goes around, and around, and doesn't really get us anywhere. Whereas Moral Shame and Moral Dread together with Compassionate Understanding, forgiveness and determination helps us to be much more active and useful. And also understands the changing nature of the self, which is more in-line with wisdom.
