Varuna is the Hindu god of the waters of the earth, both rivers and lakes and the ocean deeps.
Originally chief god of the Vedic pantheon, Varuna over time came to be demoted to lesser importance, eventually fading from popular imagination as Indra, Shiva and Vishnu gained ascendance. Varuna is associated with oaths, the upholding of the law, and maintenance of societal structure in the long term, outlasting any particular human contribution or alteration. The name Varuna was given to a TNO (Trans-Neptunian Object) in the Kuiper Belt region of the solar system, near Pluto.
Astrologically, Varuna represents law and order, the sea, and the lasting legacy one leaves behind.
