Manikut (literally "the jewel hut") is an independent room located towards the eastern end of Namghar. It is the place that houses idols representing the worshipful god, or a guru-asana (the guru's seat). It is also called as bhajghar in western Assam, with its own roof. This is the only place in Namghar that is fully walled, with or without any window. The Manikut is a later addition room attached to the basic Namghar structure.
Guru Asana
Guru Asana is the place of sacred scripture. The Guru Āsana, literally the Seat of the Guru, is a seven-tiered, triangular, wooden throne adorned by the tortoise-elephant-lion motif and other decorative woodwork.
