The Qabalah, first published in 1892, is particularly valuable because, along with his original theoretical explorations of the Qabalah, it also contains his complete translation of the Sepher Yetzirah, Eliphas Le'vi's famous Ten Lessons on the Qabalah, Rabbi Drach's important and rare treatise, The Qabalah of the Hebrews, and an extensive Qabalistic bibliography.This book gives a concise and valuable introduction to the sacred science of the Hebrews, and thus to the esoteric teachings of Christianity.

    The problems posed here often involve fundamental mathematical methods and notions, but their chief appeal is their capacity to tease and delight. In these pages you will find scores of "recreations" to amuse you and to challenge your problem-solving faculties—often to the limit.Now in its 13th edition, Mathematical Recreations and Essays has been thoroughly revised and updated over the decades since its first publication in 1892. This latest edition retains all the remarkable character of the original, but the terminology and treatment of some problems have been updated and new material has been added.Among the challenges in store for you: Arithmetical and geometrical recreations; Polyhedra; Chess-board recreations; Magic squares; Map-coloring problems; Unicursal problems; Cryptography and cryptanalysis; Calculating prodigies; … and more.You'll even find problems which mathematical ingenuity can solve but the computer cannot. No knowledge of calculus or analytic geometry is necessary to enjoy these games and puzzles. With basic mathematical skills and the desire to meet a challenge you can put yourself to the test and win. "A must to add to your mathematics library."—The Mathematics Teacher
