This classic book is part travelogue, part biography, and part exploration of Muhammad Asad (Leopold Weiss) journey towards Islam. He was an Austrian convert from Judaism to Islam in the early 20th century. His life took him across the Muslim world that changed the direction of his life. An amazing narrative with the sensibilities and powers of observation of a poet and the convictions of a convert warrior who had deeply internalized a vision of Islam. Very recommended book!
