There are two types of good books. The first is the kind that is addictive, that you plunge into and plow through-the kind you must simply and immediately complete.
The second are those which are revelatory, whose every sentence demands that you linger. Not only is it a pleasure to read twice or thrice, but a requirement. Each paragraph reveals something to you - good books of this type teach you about the world. The best teach you about yourself.
Dr Jackson has translated an introductory work of Tasawwuf, titled "Sufism for Non-Sufis?" Although pricier than one would like, it is worth having and still better to share. It is that very infrequent book that offers the wisdom of faith and the challenges it sets before us in an accessible and attractive way.
I can't recommend it enough. As always, Dr Jackson remains one of our most valuable minds. May Allah bless and preserve him and raise among us more such scholars.
