In a Shiva temple on a Maha Shiva rathri day the lamp kept in the altar was very dim. That time a mouse which came take its prey touched the flame. Due to the heat it moved its head immediately. In the process it kindled the lamp and the altar was illuminated well. Lord Shiva, pleased by this deed made the mouse Mahabali, the renowned asura king.
