PMH Atwater is the most prolific writer and most active researcher since the creation of the field of Near-Death Studies. Her web site is spectacular, and you should visit it if only to get the idea of the breadth and depth of her studies. Having endured 3 NDEs herself, her research does not stop at the subject of NDEs. An international authority on near-death states, Dr. Atwater uses the fruits of her research to establish that the near-death phenomenon is not some kind of anomaly, but is rather part of the larger genre of transformations of consciousness. She combines her 33 years of near-death research with what she was doing in the 60s and 70s, experiencing, experimenting with, and researching altered states of consciousness, mysticism, psychic phenomena, and the transformational process, to reveal what transformations of consciousness really are, why we have them, and where they lead us. This lifetime endeavor covers over 43 years of work, involving nearly 7,000 people. Her meticulous and unique protocol gives validity to what she has discovered and verified, and to the link that can be made between what is happening in the Middle East and the percentage worldwide of people who have undergone near-death experiences. A tipping point has been reached, a shared reality has emerged. . . for a leaderless, global, revolution in consciousness!
