I noticed that Dr. Schwartz will be appearing on Whitley Strieber's Dreamland, so I thought I'd offer up some thoughts on 'The Sacred Promise'--which, I think, I promised to do once I finished the book.
Short answer: It works. Following the basic premises of Dr. Schwartz's method, which I tested on many occasions in recent weeks, I received enough proof to convince me that "Spirit" seems quite real, and will tangibly intervene when asked. I won't go into detail (lack of time), but if you are receptive to this type of inquiry, I would encourage you to get the book and try it out for yourself.
The big questions, for me, are... Why? How? Why now? Is it really that simple--asking Spirit for assistance, and tangibly receiving it? If so, why now, and not in the countless millennia of human struggle and wretchedness? Where has Spirit been through all that?
Big questions, but I have a small, tentative hypothesis, one I've developed in recent years. I believe that the human race is entering a historic period--now--that, if successful, promises a convergence of what we now regard as "Spirit" with what we call "science." Science is beginning to develop the sophistication and accuracy sufficient to detect worlds that appear invisible, while the Spirit world--indeed, the larger "unknown" reality--is intervening in the physical world in increasingly bold ways. Books such as "The Sacred Promise" are really the first fruits of this synthesis of the two contrasting world views.
The promise of such a synthesis is so potentially rewarding--while a failure would be so cataclysmic--that, in my opinion, our customary rules of consensus reality are being bent slightly, to allow this opportunity for engagement.
