All and Everything or Beelzebub's Tales to His Grandson: 
An Objectively Impartial Criticism of the Life of Man
G.I. Gurdjieff
"Beelzebub" is at the very center of this teaching. Reading it is not supposed to be easy, but the direct influence of Gurdjieff can be felt within us, in our work with the contents of this book. This beautiful edition is "an unaltered republication as originally prepared by G. Gurdjieff and published in 1950."
