DHUAN, Punjabi for smoke, is a term which is particularly used for seats of certain monkish orders where a fire is perennially kept alive. In the Sikh context it is employed for the four branches of Udasi Sikhs established by Baba Gurditta (1613-38), on whom the headship of the sect was conferred by Baba Sri Ghand, traditionally considered founder of the sect. The dhuans are generally known after their respective heads who were initially assigned to different regions in north India for preaching the tenets of Sikhism as laid down by Guru Nanak.
