Today was Demise of Maulana 737th anniversary. not only in this day but in many ritual events the Sufis practis Sama Dance or Sufi Whirling.
Sufi whirling is a physically active meditation which originated among Sufis, and which is still practiced by the Sufi Dervishes of the Mevlevi order. It is a customary dance performed within the Sema, or worship ceremony, through which dervishes (also called semazens) aim to reach the source of all perfection, or kemal. This is sought through abandoning one's nafs, egos 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.
