Unlike mainstream notions of forgiveness, which frequently require pardoning the perceived wrongdoings of the others, ACIM's forgiveness is a process of publishing judgments and grievances held against oneself and others. It is a acceptance that the perceived sins and problems are rooted in the illusions of the confidence, and through forgiveness, it's possible to see beyond these illusions to the natural innocence and divinity in most being. ACIM shows that forgiveness is a road to internal peace and the main element to undoing the ego's hang on the mind.
