In this work here presented in a complete English edition for the first time the problem of knowing God is confronted in an original & stimulating way. Taking up the Prophets teaching that Ninety-nine Beautiful Names are truly predicated of God the author explores the meaning & resonance of each of these divine names & reveals the functions they perform both in the cosmos & in the soul of the spiritual adept. Although some of the book is rigorously analytical the author never fails to attract the reader with his profound mystical & ethical insights which conveyed in his sincere & straightforward idiom have made from this book one of the perennial classics of Muslim thought popular among Muslims to this day.
