A Program in Wonders, usually abbreviated as ACIM, is just a profound and powerful spiritual text that appeared in the latter half the 20th century. Comprising over 1,200 pages, this comprehensive work is not really a book but a complete program in spiritual transformation and inner healing. A Program in Miracles is exclusive in their way of spirituality, pulling from different spiritual and metaphysical traditions presenting a method of believed that seeks to cause persons to circumstances of inner peace, forgiveness, and awareness for their true nature.

The beginnings of A Program in Wonders could be traced back again to the collaboration between two people, Helen Schucman and William Thetford, both of whom were outstanding psychologists and researchers. The acim course's inception happened in the early 1960s when Schucman, who was a medical and research psychologist at Columbia University's School of Physicians and Surgeons, started to see some inner dictations. She described these dictations as via an inner voice that recognized it self as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's encouragement, she started transcribing the messages she received.

Around a period of seven years, Schucman transcribed what can become A Program in Wonders, amounting to three volumes: the Text, the Workbook for Pupils, and the Information for Teachers. The Text lies out the theoretical foundation of the class, elaborating on the core ideas and principles. The Book for Pupils contains 365 classes, one for every day of the year, designed to steer the reader through a everyday practice of using the course's teachings. The Handbook for Teachers provides more advice on how to realize and show the rules of A Program in Miracles to others.

One of the central subjects of A Class in Wonders is the thought of forgiveness. The class shows that correct forgiveness is the key to internal peace and awareness to one's divine nature. In accordance with their teachings, forgiveness is not simply a ethical or moral exercise but a essential shift in perception. It requires making move of judgments, grievances, and the perception of failure, and as an alternative, viewing the entire world and oneself through the lens of enjoy and acceptance. A Course in Miracles emphasizes that true forgiveness results in the recognition that individuals are interconnected and that separation from one another is an illusion.
