G. I. Gurdjieff taught that we are not really awake, but are entranced automatons, controlled by mechanical habits of thought, perception and behavior. Tart clearly presents the evidence for how deeply asleep we are and its consequences, and then describes methods for becoming more awake, less asleep, more spiritual, less mechanical, allowing us to realize our full potential.
Problems with spiritual teachers and groups along the way are sensitively analyzed and ways given to avoid them, so we can become more intelligent and compassionate, rather than members of some cult.
