When one reads anything produced by Schwartz one should bear in mind he is a professional writer who is dedicated to his on craft. His style is easy the reader even when you do not agree. Schwartz is a man of great passion and great integrity who should be respected even when one disagrees.
Schwartz is a Sufi Muslim and in this work his passion for his subject is quite evident. One gets to understand Schwartz as a person who is very sincere about his beliefs even if one disagrees. As a pragmatist I always have respected the peaceful practice of all religions. However, I am on a plane of existence that is somewhat below mysticism.
The thirty plus page introduction is highly entertaining and informative even though I disagree with the author on many points. Ultimately, his vision would lead to a better world but on a pragmatic level it is improbable.
