instructs the magician on the magic of cosmic spheres. If the magician places himself in any sphere with his mental body, for instance, into the zone girdling the earth in which he possibly intends to practise ceremonial magic, he can evoke, into this sphere, beings from other speres in exactly the same way as if he were doing it in our physical sphere. What laws, and the like, have to be adhered to in case of such operations in certain spheres is a question on which Zagol will give the magician exact information.
