Forgiveness means accepting the core of every human being as the same as yourself and giving them the gift of not judging them. You can be clear about whether or not a person's behavior is acceptable without judging the person. Forgiveness starts with ourselves and extends to others. Accepting that the core of your own being is as precious and wonderful as that of any other person is the greatest gift you can ever give yourself.
