After 100 years from the first presentation of the enneagram by Gurdjieff, this book offers a definitive understanding of the enneagram as a moving symbol. Deriving understanding from vast resources, this book for the first time gives a fully illustrated and empirically verifiable explanations about the construction and significance of the enneagram in terms of the following: - The Law of Three as a representation of three-fold worldview that goes against one-sided and top-down worldviews automatically accepted by many. This most basic but most neglected subject in Gurdjieff's teaching is discussed in relation to Gurdjieff's ballet, the Struggle of the Magicians, gnostic worldview as expressed in the Gospels of Judas, for example, and revolutionary worldview from complex system sciences. - The logic of three into four: This is formulated by Gurdjieff as O+C+ N=H. While the meanings given to O and C are reverse between Gurdjieff's Moscow lecture notes and the Ouspensky's records, this books follows the former. This is discussed in relation to the process of formation of understanding and also in relation to dynamisms between opposite sexes illustrated by the Struggle of the Magicians. Then the formula is applied to the enneagram, which can be seen as the doubling of three into four with outer-inner alternation, a curious twist that happens in the process of transition from the first half of the enneagram to the second half. - The Law of Seven: The asymmetrical structure of the octave and the natures of the two intervals are fully explained in relation to the above view of seeing the enneagram as the doubling of three into four with outer-inner alternation. This also explains the peculiarities of the note SOL in the octave discussed by Gurdjieff in his writing.. Based on the above understanding, the author goes further to construct an enneagram representing the Gurdjieff's vision of the harmonious development of man. The enneagram puts together the three centers model and the five centers model in illustrating the development of man up to the formation of individuality. Furthermore, the author compares the above enneagram with the enneagram of personality, which originates in the insights of Oscar Ichazo, and verifies its significance. As a result, this book for the first time clarifies the reasons behind the definitions of the nine personality types and their mapping on the enneagram. With a new look on the enneagram of personality, the author reveals the dynamics behind the formation of each personality type, illustrating dramas in traveling the path around the enneagram in terms of oppositions between the logic of survival and the logic of growth. + + + The author is the Japanese translator and publisher of Gurdjieff's complete writings and lectures, In Search of the Miraculous by P. D. Ouspensky, the complete series of Katherine Mansfield short stories, and the author of more than several books. http://gurdjieff-osho.namaste.jp/english/
