The Course is the result of the collaboration between two Columbia University psychologists: Dr. William Thetford and his colleague, Dr. Helen Schucman.
In 1965, Helen experienced what she described as a Voice which spoke clearly in her mind, saying “This is a course in miracles. Please take notes.” Helen took down over a period of seven years some 1,500 typewritten pages which became A Course in Miracles.
The ‘original edition’ is the unabridged volume of the Course as it was completed by Schucman and Thetford in 1972.
