A Program in Wonders, usually abbreviated as ACIM, is really a profound and influential spiritual text that appeared in the latter 50% of the 20th century. Comprising around 1,200 pages, that detailed function is not really a guide but a whole program in religious transformation and internal healing. A Course in Wonders is exclusive in their approach to spirituality, pulling from numerous spiritual and metaphysical traditions presenting a system of believed that seeks to lead individuals to a state of internal peace, forgiveness, and awareness for their true nature.

The origins of A Course in Wonders can be followed back to the venture between two people, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The course's inception happened in the first 1960s when Schucman, who was simply a medical and study psychologist acim at Columbia University's College of Physicians and Surgeons, started to have a series of inner dictations. She defined these dictations as via an internal style that determined itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Over a period of seven years, Schucman transcribed what would become A Class in Wonders, amounting to three quantities: the Text, the Book for Students, and the Guide for Teachers. The Text sits out the theoretical basis of the course, elaborating on the primary ideas and principles. The Book for Students contains 365 instructions, one for each day of the season, designed to steer the audience through a day-to-day training of using the course's teachings. The Guide for Educators offers more guidance on how best to realize and train the rules of A Program in Miracles to others.

Among the main styles of A Program in Miracles is the idea of forgiveness. The class teaches that true forgiveness is the important thing to inner peace and awakening to one's heavenly nature. According to their teachings, forgiveness isn't only a moral or honest training but a simple change in perception. It requires letting get of judgments, grievances, and the belief of crime, and instead, viewing the world and oneself through the lens of love and acceptance. A Course in Wonders stresses that true forgiveness results in the recognition that we are interconnected and that separation from each other is an illusion.
