Sufi philosophy includes the schools of thought unique to Sufism, a mystical branch within Islam, also termed as Tasawwuf or Faqr according to its adherents. Sufism and its philosophical traditions may be associated with both Sunni Islam and Shia Islam. It has been suggested that Sufi thought emerged from the Middle East in the eighth century, but adherents are now found around the world. According to Sufism, it is a part of the Islamic teaching that deals with the purification of inner self and is the way which removes all the veils between divine and man.
