The author of this new work on the symbology of the universe has taken as the basis of his argument that “nothing can be accepted as true which is not reducible to a mathematical statement; ... a tacit confession of faith in the law of numerical ratios, the geometry of the universe which underlies all revelation.” Consequently he translates a number of occult concepts into terms of geometrical science, shows the application of the principles of symbolism to a system of ethics and philosophy, and gives rules for the practical use of this universal symbolism in daily life. =A MANUAL OF OCCULTISM.= A Complete Exposition of the Occult Arts and Sciences by “SEPHARIAL.” With numerous diagrams and illustrations. _368 pp., handsomely bound in cloth gilt.
