Second Edition (2019), updated, illustrated and expanded to conform to the Esoteric Doctrine of Thelema. Initiation works through the formula called the Enterer of the Threshold. The Probationer must enter the pyramid of Malkuth from ?outside? to truly become a Neophyte. They must square the infinite circle of all that they are and can ever be. The 0=0 is the most important grade in the Order because it lays the foundation and provides the magical link between the outer world of Darkness and the interior world of Illuminated Souls or inner plane Adepti. It is the aim of magick to forge contacts with the latter. The Probationer degree is all about the circle of the infinite?for it has no number or sephira. The squaring of the circle applies to every grade and every sephira of the Tree of Life.
