Q.B.L.: Being a Short Qabalistic Treatise on the Nature & Use of the Tree of Life
Q.B.L.: Being a Short Qabalistic Treatise on the Nature & Use of the Tree of Life, by Frater Achad, from Red Wheel/Weiser, ISBN 1578633311. Aleister Crowley named Frater Achad his magical heir and Achad was fully expected to lead the cause of Thelemic Magick after Crowley's death—until the publication of Q.B.L. caused a rift between the two and Crowley began to distance himself from Achad. Revelatory to both the Qabalistic and Thelemic worlds at the time, the book remains a concise, lucid introduction to the Qabalah and Tree of Life for those seeking to incorporate such into their own magical system.
