Mr. Mathers justly insists on the literal rendering of the Hebrew title by the spelling Qabalah, which is no doubt correct, but lays him open to a charge of pedantry, which perhaps does not much affect him, since it would only come from superficial and possibly scoffing critics. The use of the letter Q without its usual English companion the u is sanctioned and advised, in this connection, by the learned Max Müller and other Orientalists of repute. To avoid the printing of Hebrew letters, the publisher has adopted a scheme of printing Hebrew words in English capital letters (in addition to the mode of pronunciation), after a method given by the author in tabular form. To the Hebrew scholar this gives an idea of barbarism, which is painful to the eye and sadly mars the volume, whilst it only saves the student the task of learning an alphabet of 22 letters. I differ from the author in representing the Hebrew Teth by T, while depicting the Tau by TH., the reverse would have been a closer imitation of the sounds. The Introduction includes a learned excursus upon the idea of “Negative Existence,” in which considerable light is thrown on that difficult subject; skilful definitions are added concerning the AIN, the AIN SOPH, and AIN SOPH AUR, answering in English to Negativity, The Limitless, and Limitless Light, the first essences of Deity. Several pages are devoted to a clear description of the Ten Sephiroth, the Numerical Conceptions of Godhead, and their explanatory titles; the Four Worlds of Emanation, and the component elements of a Human Soul; the Mysteries of the Hexagram as a type of Macroprosopus, the Most Holy Ancient One, or God the Father—and the succeeding mystery of Microprosopus, the Lesser Countenance, typified in the Pentagram and corresponding to the Christian Personality of the “Son of God,” are all explained at length. The series of references to the IHVH the Tetragrammaton, the Concealed Name of unknown pronunciation, form a valuable dissertation. The book is supplied with nine well executed diagrams, explanatory of the Sephiroth, the sacred names, essences of the soul, and a very perfect and complete scheme of the Sephiroth in the four worlds of emanation associated with the Vision of Ezekiel. Mr. Mathers desires to call special attention to the differentiation of the Deity in the Emanations, into the female type in addition to masculine characteristics: note the idealism of the Superior HE, Binah, the Mother, and the Inferior HE, Malkuth, the Bride of Microprosopus, the Kingdom of God (the Son of God and his Bride the Church), note that Genesis i. 26, says “let _Us_ make man in our image,” “male and female created he them;” the “_us_” is “Elohim,” a noun in the plural.
