Chalice of Ecstasy - Tapa blanda

1923. Being a Magical and Qabalistic Interpretation of the Drama of Parzival by a Companion of the Holy Grail.

Charles Stansfield Jones, also known as Frater Achad, was at one time designated to be Aleister Crowley's magical heir when Achad's magical advancement coincided with Crowley's search for a successor. A student of Crowley's Thelemic mystery schools, Jones discovered the "key" to "The Book of the Law", sourcework of Thelemic magick. His magical attainment remains both an inspiration and warning as some saw him as an Adept, beyond their understanding, while others thought him mad, or stuck in the Abyss. He is the author of many other books and articles.
