The Brahmaputra means the "Son of Brahma" and the river rises in Jima Yangzong glacier near Mount Kailash in the northern Himalayas. It enters India in the far eastern state of Arunachal Pradesh after traveling hundreds of miles across Tibet as the River Tsangpo. This is one of the largest rivers of the world and ends in Bay of Bengal. It acts as a good source of water for irrigation, fishing, rituals and for navigation.
According to Kalika Purana, there lived a sage named Shantanu and his wife Amogha. They prayed to Lord Brahma for a son and Lord Brahma impressed with their piety, blessed them with his son whom he wanted to create for the benefit of humanity. Shantanu placed the son - Brahmaputra amidst the holy mountains of Kailash, Gandhamadana, Jarudhi, and Sambaka. Brahmaputra assumed the form of a large mass of water where the Gods and heavenly maidens would have their bath. Thus, Brahmaputra is also a male river.
