Richard Rohr and Andreas Ebert have collaborated in “The Enneagram: A Christian Perspective” to add to the many efforts to introduce this time tested source of wisdom. I have learned painfully that I am in danger of making my worst mistakes when I was operating out of my “strengths”. The Enneagram helps to life up this issue in a way that helps bring to consciousness this danger. Then forewarned can truly be forearmed. The material is presented in a conversational manner making it easy to assimilate. If you don’t know much about this method of reflection this book would be a good place to start.
