The Grand Grimoire

The first part of the Grand Grimoire, like the Grimorium Verum, is simply a process for the evocation of evil spirits to obtain the enforced surrender of hidden treasure. In the second part the magician is certainly expected to give himself, body and soul, to the demon who serves him meanwhile, and there can be no hesitation in admitting that this creates a sharp distinction, not only between the Grand Grimoire and all the Composite Rituals, but also between the Grand Grimoire and the other Liturgies of Black Magic. It is only a palliation to say that the compact is worded as a subterfuge, and in reality gives nothing to the demon, who here, as so frequently in folklore, is bamboozled, receiving the shadow in place of the substance.
