The book was extremely vague and redundant. The content could be summed up with a few bullet point lists- and you can find that information for free online. The lack of explanation as to how the various metaphysical sources contribute to the HD chart was disappointing. I know that lumping together multiple complex systems (chakras, I Ching, etc) would make it difficult for someone to provide details, unless the author was an expert is all of those individual systems and could explain how each of them contributes to each specific concept of HD. The lack of real life examples makes the reading dry and superficial. I prefer astrology and enneagram, as they have specific, consistent, and anticipated reproducible results. I don’t know if it’s HD that I’m iffy about altogether or just this book. I might try another author, if they come from a more analytical approach.
