The Way of the Sufi was the best-selling follow-up introduction to Sufism by the writer Idries Shah after the publication of his first book on the subject, The Sufis. Whereas The Sufis eschewed academic norms such as footnotes and an index, The Way of the Sufi provided a full section of notes and a bibliography at the end of its first chapter, entitled "The Study of Sufism in the West". Shortly before he died, Shah stated that his books form a complete course that could fulfil the function he had fulfilled while alive. As such, The Way of the Sufi can be read as part of a whole course of study. Source: Wikipedia (en)
