Vasus are children of Manu, who is the son of Brahma, and are collectively called the Ashta Vasu or Eight Vasus. They are deities who represent the eight elements—earth, water, fire, wind, sun, sky, moon and the stars; in the Mahabharata, they are named Dhara, Aha, Anala, Anila, Pratyusha, Prabhasa, Soma and Dhruva, respectively. Vasus lived a privileged life in the heavens. But, one day, they got in trouble with the great sage Vasishta and were cursed very harshly.
