If you accept the world as authentic then what you do there defines your worth and who you are. If you judge what you have done as bad you will see yourself as a bad person with the need to atone for what has made you bad. Unfortunately, once you have judged yourself your guilt will remain for in the ego’s judgment there is no atonement. Forgiveness denies the reality of guilt and changes the worlds purpose by allowing the natural desire to love to replace the need to judge and in the presence of love you will know what is authentic.
