Book excerpt: This introduction to A Course in Miracles discusses the dynamics of the ego and its plan for salvation. It presents the undoing of the ego by the Holy Spirit's forgiveness, discussed as a three-step process. The final section treats these themes in the context of Christianity's teachings on forgiveness, as well as the example of Jesus' life, death, and resurrection. This second edition includes a new preface which discusses the use of biblical language in the Course, and an afterword enlarging on the book's discussion of Jesus.
