A Course in Wonders, usually abbreviated as ACIM, is a profound and important spiritual text that emerged in the latter half of the 20th century. Comprising over 1,200 pages, this detailed function is not only a guide but a whole program in spiritual change and inner healing. A Program in Miracles is unique in their approach to spirituality, drawing from numerous religious and metaphysical traditions to present a method of believed that aims to cause persons to a situation of internal peace, forgiveness, and awakening for their true nature.

The beginnings of A Class in Wonders can be traced back again to the relationship between two individuals, Helen Schucman and Bill Thetford, equally of whom were outstanding psychologists and researchers. The course's inception happened in early 1960s when Schucman, who was a clinical and study psychologist at Columbia University's School of Physicians and Surgeons, began to see some internal dictations. She explained these dictations as via an internal style that recognized it self as Jesus Christ. Schucman originally resisted these experiences, but with Thetford's inspiration, she began transcribing the communications she received.

Over a period of seven years, Schucman transcribed what can become A Class in Miracles, amounting to three volumes: the Text, the Workbook for Students, and the Guide for Teachers. The Text sits out the theoretical base of the program, elaborating on the core methods and principles. The Book for Pupils includes 365 lessons, one for every single time of the season, made to guide the reader through a day-to-day practice of using the course's teachings. The Um Curso em Milagres  Handbook for Teachers gives more guidance on how to realize and teach the principles of A Program in Miracles to others.

One of many main subjects of A Course in Miracles is the thought of forgiveness. The course shows that correct forgiveness is the important thing to inner peace and awareness to one's divine nature. In accordance with their teachings, forgiveness is not only a ethical or moral practice but a essential change in perception. It involves making move of judgments, grievances, and the belief of failure, and alternatively, viewing the planet and oneself through the contact of love and acceptance. A Program in Wonders emphasizes that true forgiveness results in the recognition that individuals are typical interconnected and that separation from each other can be an illusion.
