A thousand eggs of Kudru had to be incubated for a thousand years. And after a thousand years the eggs burst forth and these mighty serpents came out. Now Vinita's eggs didn't hatch and she was jealous and she was impatient. So she broke open one of the eggs and a half-formed child came out. It was supposed to have the brilliance of the sun, you know, the midday sun,. But it was not formed. The child was furious with his mother and cursed his mother that you are going to be a slave for 500 years until you are my brother. He got a job as the driver for the sun gods chariot.
