Whirling Dervish

Here is a video of whirling dervishes from Turkey. For people who are not familiar with the dervishes; this is nto a show they perform, it's a divine ritual. They pray and concentrate while whirling. They seperate their minds from this world and try to find / reach Him. They are also seekers of all kind of peace.

Whirling Dervish (wurl-ing dur-vish) n. A mystical dancer who stands between the material and cosmic worlds. His dance is part of a sacred ceremony in which the dervish rotates in a precise rhythm. He represents the earth revolving on its axis while orbiting the sun. The purpose of the ritual whirling is for the dervish to empty himself of all distracting thoughts, placing him in trance; released from his body he conquers dizziness. (source)
