This book is a deep dive to the heart of another tradition. There's insight into driving emotions you can't get from technical argument.
The destructivness of the message is hard to read, but doubly valuble as poetry where you can feel the reflection of the motives that drive familiar western values. The same regrets, the same complaints, the same sorrow for the compromise of the younger generation. The same celebration of those youngsters who live up to the older generation's values.
It was a literary insight in the preface that grabbed me, though. Something I want to adopt in my own writing:
"Islamic poetry is essentially political poetry, it's aim being not merely to describe the world but to change it."
