Bathouism (also, Bathou) is the folk religion of the Boro people of Assam in Northeast India. The name Bathou (Ba, five; thou, deep) in Boro means five principles. The five principles are: bar (air), orr (fire), ha (earth), dwi (water) and okhrang (ether). The chief deity, called Bathoubwrai (bwarai: "the Elder")—omnipresent, omniscient and omnipotent—is said to have created the five principles. Though there are other minor gods and goddesses, Bathoubwrai is considered the Supreme God. Bathoubwrai is unseen. The second most important deity is Mainao, the daughter of Bathoubwrai, who is considered as the "protector of the rice fields".
