The book's sources could be traced back to the early 1970s; Helen Schucman first experiences with the "inner voice" resulted in her then supervisor, William Thetford, to contact Hugh Cayce at the Association for Research and Enlightenment. In turn, an introduction to Kenneth Wapnick (later the book's editor) occurred. During the time of the introduction, Wapnick was scientific psychologist. Following meeting, Schucman and Wapnik spent around per year modifying and revising the material .

Another introduction, now of Schucman, Wapnik, and Thetford to Robert Skutch and Judith Skutch Whitson, of the Basis for Inner Peace. The initial printings of the book for distribution were in 1975. Since that time, trademark litigation by the Foundation for Internal Peace, and Penguin Books, has recognized that the information of the initial version is in people domain.

A Class in Wonders is a training unit; the program has 3 books, a 622-page text, a 478-page student book, and an 88-page educators manual. The products may be learned in the order chosen by readers. The content of A Program in Wonders addresses both theoretical and the sensible, even though software of the book's product is emphasized. The text is certainly caused by theoretical, and is a cause for the workbook's instructions, which are sensible applications.

The book has 365 instructions, one for every single day of the entire year, however they don't have to be done at a pace of 1 session per day. Perhaps many such as the workbooks that are familiar to the typical reader from prior knowledge, you are requested to utilize the material as directed. Nevertheless, in a departure from the "normal", the audience isn't needed to think what is in the book, or even take it. Neither the book nor the Course in Wonders is intended to total the reader's understanding; only, the materials certainly are a start.
