The sources of A Course in Wonders may be tracked back again to the relationship between two people, Helen Schucman and William Thetford, equally of whom were outstanding psychologists and researchers. The course's inception occurred in early 1960s when Schucman, who was a scientific and research psychologist at Columbia University's School of Physicians and Surgeons, started to experience some internal dictations. She identified these dictations as coming from an inner style that discovered itself as Jesus Christ. Schucman initially resisted these experiences, but with Thetford's support, she started transcribing the messages she received.

Around an amount of seven decades, Schucman transcribed what might become A Course in Miracles, amounting to three amounts: the Text, the Workbook for Students, and the Guide for Teachers. The Text lays out the theoretical foundation of the program, elaborating on the key a course in miracles lesson 1 and principles. The Book for Pupils contains 365 lessons, one for every single time of the entire year, made to guide the reader via a everyday practice of applying the course's teachings. The Manual for Teachers gives further guidance on how best to realize and show the maxims of A Course in Miracles to others.

Among the key styles of A Class in Wonders is the thought of forgiveness. The program teaches that true forgiveness is the important thing to internal peace and awakening to one's heavenly nature. In accordance with its teachings, forgiveness isn't only a ethical or honest exercise but a elementary change in perception. It requires letting move of judgments, issues, and the belief of sin, and alternatively, viewing the world and oneself through the lens of love and acceptance. A Class in Miracles emphasizes that true forgiveness contributes to the acceptance that people are interconnected and that divorce from each other can be an illusion.

Yet another substantial aspect of A Course in Wonders is its metaphysical foundation. The program presents a dualistic see of fact, distinguishing between the ego, which presents separation, fear, and illusions, and the Sacred Nature, which symbolizes enjoy, truth, and spiritual guidance. It shows that the pride is the source of putting up with and conflict, as the Holy Heart provides a pathway to healing and awakening. The goal of the class is to help people transcend the ego's limited perspective and align with the Sacred Spirit's guidance.
