Who Vishvakarma is
In the Rigveda, Vishvakarman is a question more than a person. His name means "the one whose work is everything", and it comes only five times in the whole collection, all of them in the tenth and last book. Two hymns, 10.81 and 10.82, are his. Before them the word was a title, used once of Indra and once of the Sun.
The two hymns belong to the late poets who had begun to ask where the world came from. They do not picture a craftsman at a bench. They picture a maker who is also a priest and a seer, "our father", who sat down to a sacrifice and offered up everything that exists. He has eyes on every side, a face on every side, arms and feet on every side. He has wings as well, and with his arms and his wings he presses heaven and earth together the way a smith welds metal.
Then the poet asks what nobody can answer. What did he stand on while he did it? What was the wood, and what was the tree, from which heaven and earth were cut? He tells thoughtful people to ask this in their own minds.
The second hymn calls him the maker and the disposer, the one who gave the gods their names, the one whom all other beings go to with their questions. It speaks of a first seed that the waters held, in which all the gods were together, resting on the navel of the Unborn. And it ends with a warning to the singers: you will not find the one who made all this. Something else has come between you and him. The chanters wander about wrapped in mist, their lips stammering.
That is all the Rigveda says. It gives him no family, no weapon, no city built for anyone. The Brahmanas that follow treat the name as another name of Prajapati, the lord of creatures, and they remember a king called Vishvakarman Bhauvana who once offered up all he had, the earth itself included.
What was the wood, and what was the tree, from which they shaped the earth and the sky?
