A Sufi ascetic is a person who practices a form of Islamic mysticism and dedicates their life to spiritual pursuits. The two most common terms used to describe a Sufi ascetic are DERVISH (7 letters) and FAKIR (5 letters). A DERVISH is a member of a Sufi order, while a FAKIR is an ascetic who has taken a vow of poverty. Both terms refer to someone who has devoted their life to the pursuit of spiritual enlightenment.
