Dear group...well...really Rawn specifically, but anyways, Alright, advanced question time. Rawn has already gone over the reasons for performing evocation in previous correspondences, but no-one has ever really gone over why one should evoke one particular entity over another. For when Bardon speaks of the Book of Magical Formulae the first item that he places in the forefront is 1. Purpose of the operation. Should the purpose be just to evoke the being? Learn what it has to say, to teach you? To have a sense of communion with something that is outside the normal realm of human consciousness in an attempt to expand one's own consciousness so that it can garner a better understanding of the divine? Or should it be to have the spirit perform a specific task? Something that should, most likely be practiced once a good rapport has been made with that particular spirit. Bardon states, "When the magician has become sufficiently acquainted with the zone girdling the earth, so that he has contacts with some of its heads, especially the masters of magic, he may start trying to get into contact with intelligences of the Moon sphere." How many spirits should one come in contact with to become "sufficently acquainted with the zone girdling the earth"? I know that in some areas of PME Bardon seems to imply that to master the sphere one needs to evoke quite a number, if not all of the heads of that particular sphere. Which sometimes boggles my mind given the number of spirits that Bardon lists throughout PME. If he was in personal contact with each of these spirits...even over the course of many years it would almost seem as if he would be performing an evocation or more every day over the course of at several years. Personally when I work an evocation, I often feel physically drained, and usually quite hungry afterwords. In contrast to this sense of physical fatigue there is an extreme sense of peace and exhileration upon the astral and mental bodies... Love and Live well, Peter Reist
