Lakshmi was the daughter of the sage Bhrigu and took refuge in the ocean of milk when the gods were sent into exile. Lakshmi was reborn during the Churning of the Ocean. As soon as the gods saw Lakshmi, they all fell in love with her beauty. Shiva claimed Lakshmi as his wife, but since he had already taken the Moon, her hand was given to Vishnu, whom Lakshmi herself preferred.
Lakshmi is the goddess of light, beauty, good fortune and wealth. While Laxmi is generally worshiped to achieve success, she does not reside long with anyone who is lazy or desire her only as wealth.
