The most valuable contribution to the study of Varuna is Hillebrandt's 'Varuna and Mitra.' This author has succeeded in completely overthrowing the old error that Varuna is exclusively a night-god.[78] Quite as definitively he proves that Varuna is not exclusively a day-god.
Bergaigne, on the other hand, claims an especially tenebrous character for Varuna.[79] Much has been written on luminous deities by scholars that fail to recognize the fact that the Hindus regard the night both as light and as dark. But to the Vedic poet the night, star-illumined, was bright. Even Hillebrandt speaks of the bright heaven" of day as "opposed to the dark night-heaven in which Varuna also shows himself."[80]
In the Rig Veda, as it stands, with all the different views of Varuna side by side, Varuna is a universal encompasser, moral as well as physical. As such his physical side is almost gone. But the conception of him as a moral watcher and sole lord of the universe is in so sharp contrast to the figure of the rain-god, who, like Parjanya, stands in mid-air and upsets a water-barrel, that one must discriminate even between the Vedic views in regard to him.[81]
It is Varuna who lets rivers flow, with Indra he is besought not to let his weapons fall on the sinner; wind is his breath.[82]
On the other hand he is practically identified with the sun.[83] How ill this last agrees with the image of a god who 'lives by the spring of rivers,' 'covers earth as with a garment,' and 'rises like a secret sea (in fog) to heaven'![84] Even when invoked with the sun, Mitra, Varuna still gives rain: "To whomsoever ye two are kindly disposed comes sweet rain from heaven; we beseech you for rain ... you, the thunderers who go through earth and heaven" (v. 63),—a strange prayer to be addressed to a monotheistic god of light: "Ye make the lightning flash, ye send the rain; ye hide the sky in cloud and rain" (ib.). In the hymn preceding we read: "Ye make firm heaven and earth, ye give growth to plants, milk to cows; O ye that give rain, pour down rain!" In the same group another short hymn declares: "They are universal kings, who have ghee (rain) in their laps; they are lords of the rain" (v. 68). In the next hymn: "Your clouds (cows) give
