502 MAGICK WITHOUT TEARS From the above it ought to be clear to you that I have said all that really needs to be said in explaining the whole of Magick as the science and art of extending, first in oneself, one's own faculties, secondly in external nature their hidden characteristics. Before closing the subject entirely I think it well to point out that there are quite a number of worlds on which a good deal of work remains to be done. In particular I cannot refrain from mentioning the work of Dr. Dee and Sir Edward Kelly. My own work on this subject has been so elaborate and extensive that I shall never sufficiently regret that I never had an opportunity of completing it, but I should like to emphasize that the obtaining of a book like Liber 418 is in itself so outstanding an achievement that it should serve as an encouragement to all Magicians. In the case of many worlds, in particular that of Abra Melin, of the greater and lesser Keys of Solomon, of Pietro di Abano, of Cornelius Agrippa, while we have perfectly adequate information as to the methods we have very meagre examples of the results, especially so far as refers to the technical side of the work . I must conclude with a warning. So many of these branches of magick are so fascinating that anyone of them is liable to take hold of the Magician by the short hair and upset his balance completely. It should never be forgotten for a single moment that the central and essential work of the Magicians is the attainment of the Knowledge and Conversation of the Holy Guardian Angel. Once he has achieved this he must of course be left entirely in the hands of that Angel, who can be invariably and inevitably relied upon to lead him to the further great step-crossing of the abyss and the attainment of the grade of Master of the Temple. Anything apart from this course is a side issue and unless so regarded may lead to the complete ruin of the whole work of the Magician.
