A Course in Wonders, often abbreviated as ACIM, is a profound and powerful spiritual text that appeared in the latter 50% of the 20th century. Comprising around 1,200 pages, this detailed work is not just a book but an entire program in spiritual transformation and inner healing. A Program in Miracles is exclusive in their way of spirituality, drawing from various religious and metaphysical traditions to provide a system of believed that seeks to lead persons to a state of inner peace, forgiveness, and awakening with their true nature.

The sources of A Program in Miracles may be tracked back once again to the collaboration between two individuals, Helen Schucman and Bill acim Thetford, both of whom were prominent psychologists and researchers. The course's inception occurred in the first 1960s when Schucman, who had been a medical and research psychologist at Columbia University's School of Physicians and Surgeons, began to experience a series of inner dictations. She defined these dictations as originating from an internal style that discovered it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around a period of seven years, Schucman transcribed what can become A Class in Miracles, amounting to three sizes: the Text, the Book for Students, and the Manual for Teachers. The Text lays out the theoretical foundation of the program, elaborating on the core ideas and principles. The Workbook for Students includes 365 classes, one for every single day of the season, designed to guide the audience by way of a everyday exercise of applying the course's teachings. The Handbook for Educators gives further advice on how to understand and train the maxims of A Program in Miracles to others.

One of many central subjects of A Class in Wonders is the notion of forgiveness. The program shows that correct forgiveness is the important thing to internal peace and awareness to one's heavenly nature. In accordance with its teachings, forgiveness isn't merely a moral or ethical training but a simple change in perception. It involves making move of judgments, grievances, and the notion of sin, and instead, seeing the planet and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that true forgiveness contributes to the acceptance that individuals are all interconnected and that divorce from one another is an illusion.
