What is "A Course in Miracles" (ACIM)? ACIM is a spiritual tool that comes from Jesus Christ. The Course is a practical pathway of forgiveness and love that uses the teachings of psychology, education, and Christianity. ACIM contains a Text that teaches the principles, a Workbook for practical application, and a Manual for Teachers, that we may become conduits for miracles. We need to remove our ego mask that covers our Christ Self . . .
