The sheyh was considered the most spiritually and intellectually mature member of the order. His authority was paramount, but he was assisted in his duty as head of the order or convent by a group of elder dervishes, among them the Tarikatci Dede, or chief religious guide of the order, the Ascibasi, or chief of service and the Meydanci or Master of Ceremonies, who also took an important part in the ceremonies and rituals of the order.
