Once on a time, Aditi, the mother of gods, cooked some food for her sons. She thought that, eating that food and strengthened by it, the gods would succeed in killing the Asuras. After the food had been cooked, Vudha, having finished the observance of an austere vow, came before Aditi and said her,Give me alms! Though thus solicited Aditi gave him none, thinking that no one should eat of the food she had cooked before her sons, the gods, had first taken it. Enraged at the conduct of Aditi who thus refused to give him alms, Vudha who was Brahma's self through the austere vow he had finished, cursed her, saying that as Aditi had refused him alms she would have a pain in her womb when Vivasvat, in his second birth in the womb of Aditi, would be born in the form of an egg. Aditi reminded Vivasvat at that time of the curse of Vudha, and it is, therefore, the Vivasvat, the god who is worshipped in Shraddhas, coming out of the womb of Aditi, passed by the name of Martanda.
