Researchers Newberg and D'Aquili used high-tech imaging devices to peer into the brains of meditating Buddhists and Franciscan nuns. As the data and brain photographs flowed in, the researchers began to find solid evidence that the mystical experiences of the subjects "were not the result of some fabrication, or simple wishful thinking, but were associated instead with a series of observable neurological events," explains Newberg. "In other words, mystical experience is biologically, observably, and scientifically real.... Gradually, we shaped a hypothesis that suggests that spiritual experience, at its very root, is intimately interwoven with human biology." Lay readers should be warned that although the topic is fascinating, the writing is geared toward scientific documentation that defends the authors' hypothesis. For a more palatable discussion, seek out Deepak Chopra's How to Know God, in which he also explores this fascinating evidence of spiritual hard-wiring. --Gail Hudson
This is a modest book in size but big in terms of novelty and the quality of research it represents. It is a sampling of some of the most cutting edge research (in this case, from UPenn), in brain science, meditation, and why the religious impulse simply won't go away. This is also a scientifically based argument FOR religious and mystical beliefs and practices. It is a rare gem for us transpersonalists.
