The beginnings of A Course in Miracles may be tracked back to the collaboration between two individuals, Helen Schucman and William Thetford, both of whom were prominent psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a clinical and study psychiatrist at Columbia University's School of Physicians and Surgeons, started to experience some inner dictations. She identified these dictations as coming from an internal voice that discovered itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the communications she received.

Around a period of seven decades, Schucman transcribed what would become A Program in Wonders, amounting to three volumes: the Text, the Workbook for Pupils, and the Manual for Teachers. The Text lies out the a course in miracles base of the class, elaborating on the key methods and principles. The Workbook for Pupils includes 365 lessons, one for every day of the year, developed to steer the reader through a day-to-day training of applying the course's teachings. The Guide for Educators offers further guidance on how to realize and train the rules of A Course in Wonders to others.

Among the key themes of A Course in Wonders is the notion of forgiveness. The class shows that correct forgiveness is the key to internal peace and awareness to one's divine nature. According to its teachings, forgiveness is not only a ethical or ethical training but a basic shift in perception. It requires allowing go of judgments, grievances, and the understanding of failure, and alternatively, viewing the world and oneself through the contact of love and acceptance. A Course in Wonders stresses that correct forgiveness contributes to the recognition that individuals are typical interconnected and that separation from one another is definitely an illusion.

Yet another significant aspect of A Course in Miracles is their metaphysical foundation. The course presents a dualistic view of fact, distinguishing involving the ego, which presents divorce, anxiety, and illusions, and the Sacred Heart, which symbolizes love, truth, and spiritual guidance. It implies that the ego is the source of enduring and conflict, as the Holy Spirit supplies a pathway to therapeutic and awakening. The goal of the program is to help persons surpass the ego's limited perception and align with the Holy Spirit's guidance.
