3. The Wisdom of the Enneagram by Riso and Hudson

I put this book on my "shelf" on Goodreads on November 18, 2012! I have been exposed to the Enneagram since 2011, but I had to read the "gateway drug" books like The Road Back to You first to get into the heavier material. 

I am so glad I finally got around to reading this. I kept checking it out of the library with no hope of ever getting through its almost 400 pages. I finally ordered my own copy, and I am so glad I did. I underlined so much and wrote a lot of notes in the margin. I would say this is the most comprehensive book of any of the Enneagram books I have read so far. What finally pushed me over the edge to read it was taking a 10 Week class from Russ Hudson with a live Q & A at the end. I was so IMPRESSED by this warm and generous soul that I had to read the book. I also wanted to read it because I get daily EnneaThoughts in my email, and they are often quotes from this book.

It is so comprehensive. It is not Christian because they wrote it for all faiths, but Don Richard Riso was a Jesuit priest, and you see Ignatian Spirituality coming through everywhere in the book even though there are quotes from all the different faith traditions. That might turn a really conservative believer off, but now that I took this class from Russ, I felt great about reading it. I heartily recommend this book for someone who really wants to delve deeply into this subject.
