Beelzebub's Tales to His Grandson or An Objectively Impartial Criticism of the Life of Man is the first volume of the All and Everything trilogy written by the Greek-Armenian mystic G. I. Gurdjieff. The All and Everything trilogy also includes "Meetings with Remarkable Men" and "Life Is Real Only Then, When 'I Am'". The book was intended to be the main study tool for Gurdjieff's Fourth Way teachings. As Gurdjieff's idea of "work" is central to those teachings, Gurdjieff went to great lengths in order to increase the effort needed to read and understand it. Gurdjieff himself once said, “I bury the bone so deep that the dogs have to scratch for it." The book covers many topics. It is an allegory and myth in a literary form all its own.
