having read above comments..
I will only say that "Forty Rules of Love " is a true masterpiece to date.. mysticism/ sufism is not a thing that appeals or is discerned by all.. it needs a third eye to see whats going on.. everyone has his/her own choice..

The Alchemist by Paulo cuelho

You can Win by Shiv Khera is also a very good read those who will read it will find it immensely helpful in daily life.. it is free for download on net.
