Seb-i Arus, The Wedding Day
Every 17 December, the night of Mevlana's death, thousands of people from all around the world gather at the magnificient 13th century Mevlana Mausoleum to celebrate Seb-i Arus, his 'Wedding Day', his reunion with his Beloved, with the Divine.
According to Mevlana's teachings, human beings are born twice, once of their mothers and the second time of their own bodies. The real birth is the second, spiritual birth. Mevlevi dervishes, guided by a spiritual leader, are expected to live as members of the Mevlevi Order, according to the principles of his teaching. A long period of spiritual progress is necessary before they can participate in the whirling dance, for which they wear a tall cap symbolizing the tomb of carnality, and a white robe which is its shroud.
