This is the first English translation of Eliphas Levi's Preliminary Discourse from the second edition of his famous Dogma & Ritual of High Magic (also called Transcendental Magic in English). It is a Discourse on Gnostic Kabalah: the Human Verb, the Divine Verb and Divine Humanity. It is presented in a Bilingual format (English side-by-side with the original French) with copious footnotes and a sizable Editor's Appendix.
