On Thursday May 30th, 2013 the Hermetic Hour, with host Poke Runyon, will present a discussion on the practical aspects and ritual techniques employed in the Holy Guardian Angel retreat. This is the modern three day intensive solo operation developed by Charles Russell for the G.B.G. and adopted by the O.T.A. in the 1970s as the central requirement for the Melanophoris Third Degree of our Crata Repoa system. The medieval origin of the H.G.A. retreat was the much longer vigil of "Abramelin The Mage." Our weekend intensive uses the Paths of the Tree of Life as a ritual frame work, requiring twenty-two separate rituals within the three-day time period. If done correctly and resolutely it can be the spiritual experiece of a lifetime. We will discuss the traditional background, from Hermes, through Agrippa, to Abramelin and the Pauline Art, detailing what the retreat should be and what it should not be. No one seriously interested in the art of Magick should miss this; it is the Keystone of the Great Work.
