Mohini, in Hinduism, is the female form of Vishnu. He assumes this beautiful appearance in order to entice the asuras and to get from them their share of amrta, the nectar of immortality, after the Churning of the ocean. He likewise assumed this form in order to test Vishnu when the latter was in his ascetic mode. A.G.H.
