"As for those mediums who possess magical ability, they almost always come from the most ignorant classes—Celts are an exception to this rule—and have no knowledge whatever of the technique of the business. Worse, they are usually of the type that delights in the secret dirty affinities, and so naturally and gladly attract entities of the Qliphothic world to their magical circle. Hence tricksters, of the lowest elemental orders, at the best, come and vitalize odds and ends of the Ruach of people recently deceased, and perform astonishing impersonations. The hollow shells glow with infernal fire. Also, of course, they soak up vitality from the sitters, and from the medium herself.
Altogether, a most poisonous performance. And what do they get out of it? Even when the "Spirits" are really spirits, they only stuff the party up with a lot of trashy lies." --- Crowley
