Book excerpt: This book explains in the depth the non-dualistic metaphysics of A Course in Miracles, and its integration with living in this illusory world. It demonstrates how the Course resolves the paradox of an imperfect material universe seeming to come from a perfect immaterial Creator. The study is carried out in the context of the Platonic and Gnostic themes that have run through Western intellectual and religious history, and the contrast of these with the Course.
