Devi Bhagavata Purana narrates that once Revanta, the sun-god Surya's son came to god Vishnu's abode, riding Uchchaihshravas. Seeing Uchchaihshravas - her brother's brilliant form, Lakshmi was mesmerized and ignored a question asked by Vishnu. Suspecting that Lakshmi lusted for Uchchaihshravas and thus ignored him, Vishnu cursed her to be born as a mare in her next birth.
