From the author - Dr. Ronald Grisell:It is my intention that this book should be accessible to a wide range of people from differing backgrounds. For this reason, I have presented detailed historical lineages along with a broader explanation of the theories and practices of Sufism today, with the hope that both the novice and the scholar studying the subject may gain some profit and insight from my research.From the Publisher:Presented in a easy-to-read format, Sufism not only gives a detailed account of the major practices of Sufism, but also traces the development and lineages of the faith in the major centers. Sufism also contains examples of important Sufi verse, a detailed explanation of the major religious practices, a first hand description of ceremonies at a temple and a bibliography of literature related to Sufism in English and Persian (Farsi) for serious students.
