The Divine Science is the systematic and exact process of the discovery of the mystical capabilities of the human soul. In all ancient religions and cultures the wise men and women used sacred words, the intonations of mantras, and the use of the magical art of Theurgy (mysticism or white magic). This book is filled with direct instruction and practices that anyone can use in order to discover the depth of authentic mysticism. "The Divine Science" is a compilation of three books: Logos Mantra Theurgy (1959), The Esoteric Treatise of Theurgy (1959), and The Seven Words (1953).
