In the traditions of the Sufis, Raqs, the sacred dance of spiritual ecstasy which even now is prevalent among the Sufis of the East, is traced to the time when contemplation of the Creator impressed the wonderful reality of His vision so deeply on the heart of Jelal-ud-Din Rumi that he became entirely absorbed in the whole and single immanence of nature, and took a rhythmic turn which caused the skirt of his garment to form a circle, and the movements of his hands and neck made a circle. It is the memory of this moment of vision which is celebrated in the dance of dervishes.
