[Summary] Beatrice Chestnut's book, “The Complete Enneagram,” offers a modern yet holistic framework for understanding personality and achieving self-awareness. The text begins by describing the human condition as one of "waking sleep," where unconscious habits and ingrained patterns govern our lives. It then explains the Enneagram's nine personality types, each with its unique passion and cognitive mistake, illustrating them with examples and drawing on Homer's Odyssey and Dante's Divine Comedy. Finally, it presents the Enneagram as a universal symbol of an ancient teaching, rooted in the perennial philosophy, and traces its rediscovery through the work of G. I. Gurdjieff, Oscar Ichazo, and Claudio Naranjo. The book concludes by offering a roadmap for personal growth using the Enneagram, focusing on self-observation, self-inquiry, and self-development.
