Aruna

Brother of Garuda and charioteer of Surya.

Vinata had two eggs, as no children hatched, she became impatient and broke the first one. The child wasn’t finished yet, its abdomen was not formed. Aruna left his mother and advised her to be more patient with the other egg. Garuda hatched from the other egg. Aruna became the charioteer of Surya.
