A dervish, darvesh, or darwīsh (from Persian: درویش, romanized: Darvīsh) is a Muslim who seeks salvation through ascetic practices and meditations. It can refer to an individual or to a member of a Sufi order (tariqah). Their focus is on the universal values of love and service, deserting the illusions of ego (nafs) to reach God. This is usually done by performing a lifestyle which decreases bodily function to a minimum in order to attain what would be called "esoteric knowledge" in Western terminology. In most Sufi orders, a dervish is known to practice dhikr through physical exertions or religious practices to attain the ecstatic trance to reach God. Their most popular practice is Sama, which is associated with the 13th-century mystic Rumi.
For centuries, this was an individual practice, but in the 12th century, it began to be mostly practiced in fraternities. The oldest historical fraternity is the Qadiriyya order, founded by Abdul Qadir Gilani. According to Islamic beliefs, each order derives their history from the Prophet Muhammad and are authorized by God (Allah) and taught by the angel Gabriel. The theology of such fraternities is always based on Sufism and can vary from quietism to anti-nomianism. Those adhering to law are called ba-shar and those who do not follow law are called bi-shar. In folklore, dervishes are often credited with the ability to perform miracles and ascribed supernatural powers.
