Understanding Christian Spirituality Book

I gave this 3 stars only because I don't feel like I gained any particularly profound insights from reading it. It discusses the differences--or at least society's perceived differences--between religion and spirituality, but it read like a book on systemic theology, highlighting the sources & norms of spirituality instead. I did find it interesting how the author points out that contemporary society, in its attempt to disassociate with the institutional church, has divorced spirituality and religion and flocked to other "spiritual" sources outside of the church including yoga, self-help books and psychological tests like the Enneagram. I do agree that our society yearns for a deeper self-understanding that is truly spiritual in its desire and quest and manifests itself in different ways. I suppose this would be a good introduction to Christian spirituality, but can't really see the average person reading it for pleasure.
