According to Gurdjieff, the organ Kundabuffer was implanted in human beings to prevent them from seeing the reality of their situation - that they served as food for the Moon. Kundabuffer endowed humanity at a personal level with a false sense of self-importance and an illusion of free will, which kept human beings in a state of sleep. Kundabuffer prevented people from understanding the nature of the universe and their place in it. Throughout Beelzebub's Tales to His Grandson, Gurdjieff explains how various messengers from above came down to help humanity escape the consequences of the properties of this maleficent organ. This book provides the background to this and explains the story of Kundabuffer.
