Under the Stars - Konya. Turkish whirling dervishes of Mevlevi. The way I understand it is that "Dervishes" practice an esoteric form of trance dance in conjunction with their Sufi beliefs that is meant to increase their connectivity to God.
The mausoleum of Jalal ad-Din Muhammad Rumi (qs), a Sufi mystic also known as Mevlâna or Rumi. It was also the dervish lodge (tekke) of the Mevlevi order, better known as the whirling dervishes. Mevlâna died on 17 December Konya, Turkey
