in majesty above all, though hardly a dozen hymns were addressed to him exclusively, was the deity Varuṇa. Varuṇa's name is from the verbal root vṛ, 'to cover, to encompass'; for he encompasses the universe, and his attribute is sovereignty.
Campbell identifies Varuṇa as the supreme Vedic deity in terms of cosmic majesty, grounding his name etymologically in the root meaning 'to encompass' and attributing to him sovereignty over the order of the world (ṛta).
