One of the most interesting and impressive of Vedic deities is Varuṇa, often invoked with a more shadowy double called Mitra. No myths or exploits are related of him but he is the omnipotent and omniscient upholder of moral and physical law. He established earth and sky: he set the sun in heaven and ordained the movements of the moon and stars: the wind is his breath and by his law the heavens and earth are kept apart. He perceives all that exists in heaven and earth or beyond, nor could a man escape him though he fled beyond the sky. The winkings of men's eyes are all numbered by him[152]: he knows all that man does or thinks. Sin is the infringement of his ordinances and he binds sinners in fetters. Hence they pray to him for release from sin and he is gracious to the penitent. Whereas the other deities are mainly asked to bestow material boons, the hymns addressed to Varuṇa contain petitions for forgiveness. He dwells in heaven in a golden mansion. His throne is great and lofty with a thousand columns and his abode has a thousand doors. From it he looks down on the doings of men and the all-seeing sun comes to his courts to report. There is much in these descriptions which is unlike the attributes ascribed to any other member of the Vedic pantheon and recalls Ahura Mazda of the Avesta or Semitic deities. No proof of foreign influence is forthcoming, but the opinion of some scholars that the figure of Varuṇa somehow reflects Semitic ideas is plausible. It has been suggested that he was originally a lunar deity, which explains his association with Mitra (the Persian Mithra) who was a sun god, and that the group of deities called Âdityas and including Mitra and Varuṇa were the sun, moon and the five planets known to the ancients. This resembles the Babylonian worship of the heavenly bodies and, though there is no record whatever of how such ideas reached the Aryans, it is not difficult to imagine that they may have come from Babylonia either to India[153] or to the country where Indians and Iranians dwelt together. There is a Semitic flavour too in the Indian legend of the Churning of the Ocean[154]. The Gods and Asuras effect this by using a huge serpent as a rope to whirl round a mountain and from the turmoil there arise various marvellous personages and substances including the moon. This resembles in tone if not in detail the Babylonian creation myths, telling of a primæval abyss of waters and a great serpent which is slain by the Gods who use its body as the material for making the heavens and the earth[155].
