Vinata was one of the wives of rishi Kashyapa, and she bore him two sons, Aruṇá and Garuda, bringing them out as eggs. Vinata was promised that her sons would be powerful if she waited for them to hatch from their eggs. However, her impatience to hatch them took root, and she broke one of them. From the broken egg a flash of light, Aruṇá, sprang forth. He was as radiant and reddish as the morning sun. But, due to the premature breaking of the egg, Aruṇá was not as bright as the noon sun as he was promised to be. Aruṇá's brother, Garuda, was born regularly, and eventually became the main vehicle of Vishnu.
