Dervishes of the whirling variety are most famously associated with Turkey, where they’ve become something of a tourist attraction throughout the country. But the dervish tradition extends far beyond modern-day gawkers and Turkey’s borders. Dervishes are Sufi Muslims who lead an ascetic lifestyle. Whirling dervishes spin rhythmically in order to reach a state of religious or spiritual ecstasy, and are found in many places outside of Turkey. In fact, the whirling dervish ceremony just outside of Khartoum, Sudan, where Flickr user Mark Fischer snapped this photo, is one of the most popular tourist attractions in the capital.
