A very casual look into the "world" and "thinking style" of Sufis, as seen from an open-minded psychologists perspective. The book does not offer lessons in the Sufi way, nor does it inspire or recommend anything to the reader in particular. It, more or less, takes a broad and wide-angled look at Sufiism in a general manner.
Excellent language is used, and the authors desired effect of shining the light on the existing effects of Sufiism on this world consciousness is achieved.
