A Course in Miracles is a modern spiritual teaching that has become the path to God for thousands of people. The Course employs a unique use of language in which it fills familiar terms with new–often radically new–meaning. This has the double effect of making its language initially confusing yet eventually transformative. Hence the need for a glossary, which can help the student graduate from that initial confusion into experiencing the full psychological effect of the Course’s language and teaching. Containing nearly 200 definitions of Course terms, word pairs, and phrases, this glossary is intended both for beginning students and more experienced students and can aid both individual and group study.
