In the Ismaili tariqah, the guardian of each Jamatkhana is called mukhi (in the South-Asian tradition) or Sheikh (in the Arab tradition) there are also other names that are applied based on the cultural context of the Jamat, mukhi is a word derived from mukhiya means foremost. Since the Imam physically is not present all the times in the Jamatkhana, the Mukhi acts the tangible symbol of the Imam's authority. In the big jamat, the Mukhi was assisted by a caretaker called tha'nak. Later, the office of kamadia (from kamdar accountant) was created. The Mukhi and Kamadia are the traditional titles going back to the pre-Aga Khan period when they enjoyed considerable local power. Their responsibilities include officiating over the daily rituals in the Jamatkhana, but they are primarily lay officials. Since the wholesale reorganizations undertaken by the Imams, the local committees are now tied into an elaborately hierarchical administrative structure of boards and councils.
