Sufi whirling is a form of physically active meditation which originated among certain Sufi groups, and which is still practiced by the Sufi Dervishes of the Mevlevi order and other orders such as the Rifa'i-Marufi. It is a customary meditation practice performed within the sema, or worship ceremony, through which dervishes aim to reach greater connection with Allah. This is sought through abandoning one's nafs, ego or personal desires, by listening to the music, focusing on God, and spinning one's body in repetitive circles, which has been seen as a symbolic imitation of planets in the Solar System orbiting the Sun.
