As a cross-reference tool for determining the underlying causes of an ailments, I've found this book to be quite insightful, if not ahead of it's time. For example, I found it very interesting that many of Edgar Cayce's remedies included methods for dealing with digestion-related problems, elimination of accumulated toxins, and restoration of a person's acid/alkaline balance. These factors are increasingly being found to be connected to many of the same diseases that Cayce referenced in this book, from asthma and gallstones, to cancer. In my opinion, his readings went far beyond ordinary common sense, particularly for his day.
