The book is really good but poems of Moulana Rumi should be translated into Urdu which will give us the thought of Moulana Rumi in a clear vision.
I'm satisfied with the quality of publishing. As far as the content is concerned, Shibli doesn't cite the source of each claim separately, and it's hard, therefore, to distinguish between baseless and sound claims about Rumi's life. His analysis of the Masnavi, nevertheless, is remarkable. Overall, it's a good introduction to Rumi's life and works.
