This book is fantastic for those who want a book not necessarily just about anxiety, but about really becoming in tune with your physical, emotional, spiritual, and intellectual needs. It has a Christian undertone (he is a Christian author) but the book doesn't necessarily promote any religion but speaks of spirituality in general.
It has gone through my entire extended family,a nd we all love it. I really really suggest reading it (or get it on audio cd cheap from amazon.com or another site like that) or listening it in your car on the way to work, road trips, etc. It will change your life! It's very profound, so I listened to small bits at a time to absorb it in.
