““One of the greatest assets of this present work is the meticulous attention paid to the subject of theurgy or "god working," which Leitch describes as "the heart of our work." Theurgy is designed to elevate the magician's soul toward the celestial realms by invoking and communicating with angels, archangels, and various levels of deity. The detailed regimen of magical work, purity, humility, and self-control required of a medieval theurgist should leave the reader with little doubt that the spiritual path of the adept magician is a high caliber discipline that takes work, perseverance, and dedication.””
