It's finally done! I ended up self-publishing (for now) as 8 publishers weren't interested -- only 3 of them having the decency to say so (the other 5 still haven't replied after months). - see http://shalomplace.com/view/godandi.html for order options.
I consider this to be something of my "opus magnus" -- the culmination of years of reflection and study. It will be foundational for a book on kundalini and Christianity that I will be writing during the next year or so, as it will provide the anthropology necessary to situate kundalini in a human, spiritual context (open to grace, psyche and body).
Thanks to those of you who provided feedback during the writing process. I will be sending you the pdf copy soon.
