The Book of Concealed Mystery is a mystical text written by S. L. MacGregor Mathers, a prominent member of the Hermetic Order of the Golden Dawn. The book is a translation of a medieval Hebrew text called the Sepher ha-Razim, which contains a collection of magical spells, incantations, and rituals. The book is divided into two parts, the first of which focuses on the creation of the universe and the nature of the divine. The second part deals with practical magic, including the use of amulets, talismans, and invocations to summon angels and demons. The book is considered to be one of the most important works of Jewish mysticism and has been influential in the development of Western esotericism. It is a must-read for anyone interested in the history of magic and the occult.THIS 74 PAGE ARTICLE WAS EXTRACTED FROM THE BOOK: Kabbalah Unveiled, by S. L. MacGregor Mathers.
