Here’s the mantra that a student of A Course in Miracles (acim.org) created that the CATs use all the time. Look at the person (in front of you, or in your mind’s eye, etc.) and think:

You are perfect, immortal spirit, brother
whole and innocent.
All is forgiven and released.

(Note: The above is nonvocalized — a mantra — versus a mantram, which is vocalized.)

This mantra heals your mind and the forgivee’s mind, simultaneously, the Holy Spirit stepping in and healing time and space and karma around you. Each time you do this you create a MIRACLE, hence the title. It’s all about the miracle of forgiveness and healing your mind.
