The practice of Sufi whirling (or Sufi spinning), (Arabic: رقص سماع) is a twirling meitation that originated among Sufis, which is still practiced by the Dervishes of the Mevlevi order. It is a symbolic ritual through which dervishes (also called semazens) aim to reach the "perfect" (kemal). They try to desert their nafs, egos or personal [bad] desires by listening [to their master and sufi music], thinking [about God] and whirling which resembles the rotation of other beings such as electrons and planets of the micro- and macrocosmos.
