'Our work has two parts; in the one we establish the Kabbalistic and magical doctrine in its entirety; the other is consecrated to the cultus, that is, to ceremonial magic. The one is that which the ancient sages termed the clavicle, the other that which rural people still call the grimoire. The numbers and subjects of the chapters, which correspond in both parts, are in no sense arbitrary, and are all indicated in the great universal key, of which we give for the first time a complete and adequate explanation. Let this work now go its way where it wills, and become what Providence determines; it is finished, and we believe it to be enduring, because it is strong, like all that is reasonable and conscientious. Eliphas Levi'
