The great Turkish philosopher Mevlana, who believed in human love and said that mystical unity with God could be reached by the Sema, a whirling dance to music performed by the dervishes, lived in Konya and established a following here.Every year in December, Konya holds a Mevlana Week which includes performances of the Sema. Mevlana is buried with his father Bahaeddin Veled in the Green Tomb (Yesil Turbe), which has become the symbol of the city. The Dervish Lodge and Mevlana Museum adjacent to the tomb are open to the public.
