The Book of the Sacred Magic of Abramelin the Mage is a 15th-century grimoire, or book of magic, that includes instructions on how an individual can make contact with their Holy Guardian Angel.Few occultists have dared to follow the instructions, known as the operation, hidden within the text. Fewer yet have been successful. Even the famous Aleister Crowley failed to complete it.Over a six-month period in 1977, Ramsey Dukes attempted the Abramelin operation. The Abramelin Diaries is his account of what transpired when he attempted to contact his Holy Guardian Angel. It provides a retrospective commentary on what the operation did for Dukes, along with its value and significance. It also includes a brief history of The Book of the Sacred Magic of Abramelin the Mage and its magical tradition.This is a book for serious occultists only.
