There was a hermitage belonging to the sage Salankayana. He went one morning to river Ganga to bathe. As he was reciting stanzas in praise of the Sun, he saw a kite carrying a mouse in its claws. At once, the sage aimed a stone at the kite. Hit by the stone, the kite released its prey and the mouse at once ran to the sage asking him for protection.

The female mouse then prayed Salankayana, "O sage, please give me shelter in your hermitage. Otherwise, some wicked bird will kill me. I will spend the rest of my life with whatever leftovers you choose to feed me with."

The female mouse’s prayer moved the sage but he thought that if he took her home, people would laugh at him. So, he turned the mouse into a beautiful girl and took her home.

"What is this you have brought," asked the sage’s wife. Where did you bring this girl from?"

"She is a female mouse. She needed protection from wicked birds. That’s why I turned her into a girl and brought her home. You will need to shower all care on her. I will make her a mouse again," said the sage.

"Please don’t do that," pleaded his wife, "You have saved her life and therefore you have become her father. I don’t have a child. Since you are her father, she becomes my daughter." The sage accepted her plea.

The girl grew into a beautiful woman and became an eligible bride. Salankayana told his wife, "The girl has come of age. It is not proper for her to remain in our house."

"It’s all right. Look for a boy," said his wife.

Salankayana immediately summoned the Sun and told him, "This is my daughter. If she is willing to marry you, get ready to marry her."

He then showed the Sun to his daughter and asked her if she would marry him. She said that the Sun was very hot and she would prefer someone else. The sage then summoned the God of Clouds, the God of Wind and the God of Mountains. The girl rejected every one of them on one ground or the other.

Then the God of Mountains told the sage, "The most suitable candidate for your daughter is a mouse. He is more powerful than I am."

The sage then turned her into a mouse and gave her away to a king of mice in marriage.
