Provided by The Circle of Atonement and Robert Perry, this glossary of terms helps to clarify and define the words used within the Course. "The Course employs a unique use of language, a use which initially is quite confusing. When the reader first opens the book, he or she notices many terms which are very familiar, yet which do not appear to entirely fit their context; they don't seem to make sense in the way they are used. Since this occurs quite frequently, whole sentences and paragraphs become problematic and confusing.
There is, however, a reason for this confusing habit of the Course. The meaning that we assign to words grows out of the meaning we see in life—in ourselves, in others, in the world. Yet this is the very meaning which the Course wants to transform, the very meaning which clouds our sight and makes us suffer. What the Course does, therefore, is to take the same words we use and fill them with new meaning, meaning which expresses the thought system the Course seeks to instill in our minds." -CoA Glossary Introduction
