Sufism

Sufism is a mystic tradition of Islam encompassing a diverse range of beliefs and practices dedicated to Allah, divine love and sometimes to help a fellow man. Tariqas (Sufi orders) may be associated with Shi'a Islam, Sunni Islam, other currents of Islam, or a combination of multiple traditions. It has been suggested that Sufi thought emerged from the Middle East in the eighth century, but adherents are now found around the world. Some Sufis have also claimed that Sufism pre-dates Islam and some groups operate with only very tenuous links to Islam.
