The ability to accomplish this Great Work requires a great deal of preparation and effort, according to Crowley's system. The programme consists of several key elements, including a thorough knowledge of the Hermetic Qabalah (especially the Tree of Life), disciplined concentration (i.e. meditation), the Development of one's Body of Light (or astral body) (in order to experience other spiritual realms) and the consistent and regular Invocation of certain deities or spiritual beings.
