In this book, which has been called a synthesis of his whole message, Frithjof Schuon invites us to explore aspects of humankind's relationship with the Divine, including our sense of the sacred, the conditions of our existence, the symbolism of the human body, and the question of accepting or refusing God's message. In doing so, Schuon paves the way for a true spiritual engagement. This revised edition has been fully retranslated and contains valuable editor's notes and a glossary, plus a fascinating appendix of previously unpublished writings.
