The book is written in the form of an epistle to his magical son, Charles Stansfeld Jones, Frater Achad, whom Crowley later doubted as being his true magical son, asserting that Achad had in fact gone insane, citing as evidence Achad's "upending the tree of life" in his Q.B.L., or The Bride's Reception, the first of Achad's major qabalistic works. This is an cult classic and we believe it should be mandatory reading. Condition is very good, however there is a crease/fold on the corner of the front cover.
