THE KEY OF THE MYSTERIES the vision indicates a transitory perturbation of the nervous apparatus in its relation to imagination and light. If this perturbation were frequently repeated, he would become seriously ill. Who knows how many collapses, attacks of tetanus, insanities, violent deaths, the mania of table-turning has already produced? These phenomena become particularly terrible when per- versity takes possession of them. It is then that one can really affirm the intervention and the presence of the spirit of evil. Perversity or fatality, these pretended miracles obey one of these two powers. As to qabalistic writings and mysterious signatures, we shall say that they reproduce themselves by the magnetic intuition of the mirages of thought in the universal vital fluid. These instinctive reflections may be produced if the magic Word has nothing arbitrary in it, and if the signs of the occult sanctuary are the natural expressions of absolute ideas. It is this which we shall demonstrate in our book. But, in order not to send back our readers from the unknown to the future, we shall detach beforehand two chapters of that unpublished work, one upon the qabalistic Word, the other upon the secrets of the Qabalah, and we shall draw conclusions which will complete in a manner satis- factory to all the explanation which we have promised in the matter of Mr. Home. There exists a power which generates forms; this power is light. 181
