The Sarasvati River is one of the main Rigvedic rivers mentioned in the scripture Rig Veda and later Vedic and post-Vedic texts. It plays an important role in Hinduism since Vedic Sanskrit and the first part of the Rig Veda are regarded to have originated when the Vedic people lived on its banks, 2nd millennium BCE . The goddess Sarasvati was originally a personification of this river but later developed an independent identity.The Nadistuti hymn in the Rigveda mentions the Sarasvati between the Yamuna in the east and the Sutlej in the west, and later Vedic texts like Tandya and Jaiminiya Brahmanas as well as the Mahabharata mention that the Sarasvati dried up in a desert. The Sarasvati is also considered by Hindus to exist in a metaphysical form, in which it formed a confluence of the sacred rivers Ganges and Yamuna, at the Triveni Sangam. The name Sarasvati was also given to a formation in the Milky Way.
