This book is an introductory study of mysticism in the Christian religion. It should be suitable for both general readers and college undergraduates. It provides both a theory of mysticism and surveys of its main contours in Buddhism and traditional religious cultures. It also suggests how readers may understand and appreciate what mysticism implies for their own lives. This book, therefore, is addressed not only to persons called Christian, but also to the enquiring among the cultured despises of this religion. To the latter, it says: ?This is what Christians as such are talking about?; and it addresses these enquiring ones not first of all with a view to convincing them.
