Anasuya

In Hindu mythology Anasuya is the wife
of the sage Atri. On one occasion
Anasuya is begged by the gods Brahma,
Vishnu, and Shiva to help them. A
woman named Silavati has cursed the
sun not to rise, and the creatures on
earth are very distressed. Anasuya succeeds in persuading Silavati to recall her
curse, and in their gratitude the three
gods tell her she can ask for whatever she
wants. Anasuya requests that each be
born as one of her sons, and this is granted:
Vishnu is born as Dattatreya, Shiva as
Durvasas, and Brahma as Chandra.
