The list author says: "This is a list of biographies and autobiographies that I've read which have left an indelible imprint on my mind or my heart, or both. I would also add to this the magnificent Urdu book, Zindarud, which is the definitive account of the life of Sir Dr. Muhammad Iqbal and also Josh Malihabadi's Yaadon Ki Baraat, a unique biography in the history of Urdu literature."
"The most influental spiritual autobiography in Sufism, and a monumental work of Islamic civilisation, the cultural and historical importance of this slender volume is difficult to overestimate. A true classic."
"Martin Lings' other classical work this has become one of the standard texts for any student of Sufism and for anyone interested in spirituality. A detailed look at the life of one of the modern saints."
"The classic spiritual biography of Christendom in my opinion. A wonderfully awe-inspiring read, it is very instructive to compare it alongside the spiritual biographies of Ghazali and Ruzbihan, listed above."
"For sheer beauty of language, candour, and depth of expression this revealing section of Anais Nin's life is a must-read and very erotic to boot. Out of all the parts of her "Dairies" this one is the most poignant."
"A fascinating biography about the most interesting member of the Cambridge Five spy ring and a distant cousin of HRH the Queen! A great book to have read prior to reading John Banville's roman-a-clef, The Untouchable."
