Who The Ribhus is
The Ribhus are three brothers, Ribhu, Vaja and Vibhvan. Eleven hymns of the Rigveda are theirs, and their names come up more than a hundred times. What sets them apart from the other gods is that they were not born gods. The hymns say so plainly: they were mortals, sons of a man named Sudhanvan and descendants of Manu, and they earned their place in heaven with their hands.
The poets count five works and repeat them in almost every hymn. For the Ashvins the brothers built a chariot that rolls round the sky on three wheels, without horse or rein. For Indra they made the two bay horses that draw his car, "yoked by a word". They took the hide of a cow and brought a living cow out of it, and set her beside her calf again. Their own father and mother had grown so old that they lay "like posts that moulder"; the Ribhus made them young. And they took the one cup of the gods, the work of the craftsman Tvashtri, and made it into four.
The gods were pleased with all this. One hymn says that Vaja became the craftsman of the gods, Ribhukshan of Indra, and Vibhvan of Varuna. Savitr, the Sun, gave them immortality. They were given a share in the sacrifice, and it is still theirs: the third pressing of Soma, the one poured in the evening.
There is one more thing the hymns say of them and do not explain. After long wandering the brothers came to the house of Agohya, the one who cannot be hidden, and slept there for twelve days. While they rested, fields became fertile, rivers ran, and grass grew on the high ground.
The poets held them up as proof that work is honoured. "Not without toil," one hymn says, "are the gods inclined to friendship."
By the skill of your hands you became gods, and you settled in heaven like falcons coming down to rest.
