After spending his entire life teaching a system of knowledge that he transmitted to only a small circle of disciples, Georgi Ivanovich Gurdjieff decided shortly before his death in October 1949 to publish the first series of his books, "All and Everything". Here his ideas take the form of a cosmological epic, a supra-cosmic adventure based on the myth of "Beelzebub" whose exile in our Solar system, before his final return to his birthplace, brings him into contact with the human race, describing their strange customs and problems with deep sympathy and often with wonderful humor. The "omniscient Beelzebub", with his profound understanding of the weaknesses of human nature, shows the path that can lead to the transformation of man, through the development of his inner potential and presents a teaching of rare value. This book rediscovers the path that man was destined to follow within the cosmic plan, from which he has strayed so far. There is no person who has ever come into contact with Gurdjieff and has not been impressed by him and by the extent of his knowledge. There is no doubt that Gurdjieff has an important message for humanity, in this critical period of its history.
