The Brahmaputra is believed to have two mythological fathers – Lord Brahma and sage Shantanu. In the 16^th-century text Yogini Tantra, dedicated to the worship of goddesses like Kali and Kamakhya, the river is linked to an ancient ablution ritual with the following invocation:
O Son of Brahma! O Son of Shantanu! O Lohit! O Son of Lohit!
I bow before you, wash away my sins of the last three births.
