You talk a lot about anger-reduction through forgiveness, but I do not think my primary emotion is anger. I am sad. Is the forgiveness process different if I am angry compared to my being sad?
Actually, the process of forgiveness will be the same whether you are angry or sad. You still will: a) commit to do no harm to the one who hurt you; b) try to see the inherent worth of the other; c) bear the pain so you do not pass that pain to the one who hurt you or to other people; and d) try to be kind, as best you can, toward the person. What may change is the outcome for you, with a reduction of sadness rather than anger.
