The new book by Chic & Tabatha Cicero, “Golden Dawn Magic: A Complete Guide to the High Magical Arts,” is an introduction to the practices of the Hermetic Order of the Golden Dawn: its unique selling point is that it goes into slightly more depth than other such introductory guides. So for example, it does not simply describe the Lesser Banishing Ritual of the Pentagram, or the Middle Pillar Ritual, but outlines preliminary exercises of which a practioner could make use in order to get used to those rituals beforehand.
Moreover, advanced techniques such as god-form assumption, tarot divination, etc are mentioned, and the results are combined to show a Golden Dawn magician would formulate a complete “Z2” Magic of Light Ritual.
It is probably most helpful to think of this as a companion volume to the Ciceros’ “The Essential Golden Dawn,” the difference being that the former book outlines the theory, whilst the latter the practice. Nevertheless, it is at the end of the day only an introduction, and as such the authors continually refer to their other publications as shedding more light on the subject, for example: Self Initiation into the Golden Dawn; Tarot Talismans; as well as Israel Regardie’s The Golden Dawn itself.
