Vasus

In Hinduism, the Vasus are attendant deities of Indra, and later Vishnu. They are eight elemental gods representing aspects of nature, representing cosmic natural phenomenon. The name Vasu means 'Dweller' or 'Dwelling'.There are varying lists of the eight Vasus in different texts, sometimes only because particular deities have varying names. The following are names and meanings according to the Brihadaranyaka Upanishad and according to the Mahabharata as normally equated: Though the Shatapatha Brahmana uses the Brhad-Aranyaka names, most later texts follow the Mahabharata names with the exception that Āpa 'water' usually appears in place of Aha. The Vishnu Purana equates Prabhāsa with the lights of the 27 or 28 Nakshetra (Constellations/Lunar Mansions) and Dhruva with Akash Tatwa, that is "space", Dhruva seemingly taking over Aha's role when Aha is replaced by Āpa.
