“Sorcery is a deliberate act of causing metamorphoses by the employment of elementals. It forges a link with the powers of middle nature, (i.e. The astral plane, between the spiritual and physical realms.) or the ether, the astrals of great trees and of animals of every kind. Will is our medium, Belief is the vehicle, and Desire is the force combining with the elemental. Cryptograms are our talismans and protectors”
