Charles Robert Stansfeld Jones (1886-1950), aka Frater Achad, was an occultist and ceremonial magician. An early aspirant to A∴A∴ (the 20th to be admitted as a Probationer, in December 1909) who "claimed" the grade of Magister Templi as a Neophyte. He also became an O.T.O. initiate, serving as the principal organizer for that order in British Columbia. He worked under a variety of mottos and mantonyms, including V.I.O. (Unus in Omnibus, "One in All," as an A∴A∴ Probationer), O.I.V.V.I.O., V.I.O.O.I.V., Parzival (as an Adeptus Minor and O.T.O. Ninth Degree), and Tantalus Leucocephalus (as Tenth Degree O.T.O.), but he is best known under his Neophyte motto Achad (Hebrew "unity", אחד), which he used as a byline in his various published writings.
I'm not sure who this book is actually written by, but it's NOT by the well known Frater Achad, Charles Stansfield Jones, student of Aleister Crowley and author of ''Anatomy of the Body of God'', QBL, the Egyptian Revival, Liber 31, et al. It is horrific New Age/Sew-Age and should be avoided.
