I just finished Eben Alexander's "Proof of Heaven" (in fact, I'll post a comment in the books thread). This was absolutely fascinating. He's a neurosurgeon formerly from Harvard who used to think that his patients' near-death experiences were a function of the brain, and that the brain creates consciousness. Then he contracted bacterial meningitis, which ate away at his neocortex -- the part of the brain that "makes us human," he says. He lapsed into a seven-day coma and was in essence brain dead. But he writes that he never felt so alive. He explored other dimensions, and what he believed was "heaven," but says it's vaster and more complex than we could ever imagine, and that it includes many universes. His main point was that "all that is" is driven by love, which would kind of negate the idea that you have to be "good" to get in. But yet our human thoughts -- such as humor and irony -- are even more present in that realm. Needless to say, he now believes that conciousness creates the brain.
To me, this book flipped on a light switch in much the same way that "The Nature of Personality Reality," by Jane Roberts did when I was in my 30s. I have no doubt that our spirit survives our flesh, and part of me can't wait to explore other dimensions. I want to travel in time. I want answers to mysteries. I want to see my brother and maybe visit other planets. How cool would that be?
