This is an excellent book. It is an inspiration for most aspects of life, especially in difficult times. We did a group reading with my Catholic prayer group friends. We decided to re-read it after 12 years one more time.
It is a great example of the spiritual values transcending traditional religions. Very consistent with Vedic teachings and the mystical traditions of all Abrahamic religions.
May the Rebbe who is the source of this book, rest in God's light.
