I laughed when I saw the reference to Perennial Philosophy. My Spiritual Book Group just bailed out on the book because we found it so dull and impossible to read. We just spent almost 6 months on"The Evolution of God" by Robert Wright so maybe we needed something lighter. We meet weekly which is a lot for a reading group but our discussions are wonderful because we are a bunch of very savy and smart women who love to read.
Perennial Philosophy had fabulous reviews so I will give it another try.
