The sources of A Course in Miracles could be tracked back again to the collaboration between two persons, Helen Schucman and Bill Thetford, equally of whom were prominent psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a medical and study psychologist at Columbia University's University of Physicians and Surgeons, began to see a series of internal dictations. She identified these dictations as coming from an internal voice that identified itself as Jesus Christ. Schucman initially resisted these activities, but with Thetford's support, she began transcribing the messages she received.

Over a period of eight years, Schucman transcribed what might become A Class in Wonders, amounting to three sizes: the Text, the Workbook for Students, and the Handbook for Teachers. The Text lays out the theoretical base of the program, elaborating on the key ideas and acim. The Book for Students contains 365 classes, one for every day of the year, designed to steer the reader via a everyday training of applying the course's teachings. The Manual for Educators offers further guidance on how to realize and train the concepts of A Program in Wonders to others.

One of many key themes of A Program in Wonders is the idea of forgiveness. The program teaches that correct forgiveness is the key to internal peace and awakening to one's heavenly nature. According to its teachings, forgiveness is not simply a ethical or ethical exercise but a simple shift in perception. It involves allowing move of judgments, issues, and the notion of failure, and instead, viewing the planet and oneself through the contact of love and acceptance. A Course in Miracles highlights that true forgiveness leads to the acceptance that we are all interconnected and that separation from one another is definitely an illusion.

Another significant part of A Program in Miracles is its metaphysical foundation. The course gift suggestions a dualistic see of fact, unique involving the vanity, which represents separation, concern, and illusions, and the Holy Heart, which symbolizes enjoy, reality, and spiritual guidance. It shows that the vanity is the origin of enduring and conflict, whilst the Sacred Heart provides a pathway to healing and awakening. The target of the course is to help individuals transcend the ego's restricted perspective and align with the Holy Spirit's guidance.
