Query: everything you need to know under one cover

Barbara Harris Whitfield was in the perfect position as a researcher and near-death experiencer in the early 90s to understand what so many of us couldn't -- that we're not going crazy after a spiritual awakening! Instead of reading a dozen books to understand the after effects of awakening -- she has it all in one. The best part for me is that she doesn't separate herself as a researcher and clinician. She talks about all this first person. There have been many books written on this subject since hers was published in 1995, but Ms. Whitfield's is still the one that has it all under one cover.
