Started looking into the notion of forgiveness after seeing a doco. in which a holocaust survivor confronted and forgave a former camp guard.
The lady said that forgiveness is powerful and psychologically healthy. She also made a point about hatred; the object of your hatred may not even know how you feel. Not hurting them. However, carrying hatred and becoming bitter does hurt the hater.
I have hated, and do still hate but have let go of most of it. Most of the people I hated are now dead. There is only one left to forgive; my ex wife caused me greater hurt and mental anguish than any other person. . I’ve tried, but have not yet been able to let go of my hatred and bitter feelings towards her completely. I’ll keep trying.
The article linked below comes from the Mayo clinic and is rationally based rather than woo based.
This post is my opinion only, not something about which I will argue.
“Forgiveness: Letting go of grudges and bitterness
When someone you care about hurts you, you can hold on to anger, resentment and thoughts of revenge — or embrace forgiveness and move forward.”
