The hermits were disciples of a Guru Yadnyavalkya, who was always absorbed in meditation, and followed rigorous self-discipline.
One day, while he was bathing in the river, a hawk flew over with a mouse in its claws. Suddenly, the mouse fell from the hawk's grip right into the hands of the Guru.
When the Guru noticed that the hawk was flying above, he knew he cannot leave the mouse alone, or he is to be caught again. He put the mouse on a leaf of a nearby Banyan tree, and took a second bath to purify himself.
He used his powers to transform the female mouse into a little girl, and took her to the hermitage.
Thus, the girl started growing in the hermitage, under the care and supervision of the Guru himself. She learnt many sciences, and ways of life.
One day, the Guru's wife brought into his notice that their girl had reached marriageable age. They decided to give it a serious thought, as she was a special child and deserved a special husband.
But the daughter said, "Father, the Sun God lights up the entire world, but he is unbearably hot and fiery-tempered. I do not wish to marry him. Please seek a better husband for me."
