“Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else: you are the one who gets burned.” Buddha
Forgiveness is the intentional process where the victim undergoes a change in feelings and attitude regarding an offence and decides to let go of negative emotions such as vengefulness, with an increased ability to wish the offender well. This does not necessarily mean you become friends with the wrongdoer but there is peace on the side of the victim. It’s a complicated grace that uncomplicates your anger to help you see beauty again. Big job though.
