Lakshmi Narayana is the Supreme Lord, who appears along with his divine consort, Lakshmi devi. Lord Narayan is usually seen holding a conch, mace, lotus and the Sudarshana Chakra. Goddess Lakshmi is seen either standing next to a standing Lord Narayana, or at his service in their heavenly abode of Vaikuntha. Also known as ‘Shri’ or ‘Shridevi,’ she is the goddess of wealth and fortune and the very embodiment of auspiciousness and prosperity. It is also said that while Narayana is the protector, Lakshmi is the embodiment of compassion.
As the protector of the universe, the Lord incarnates on earth from time to time, to annihilate evil and to establish dharma, the ultimate righteousness. While Goddess Lakshmi, who is inseparable from him, remains part of him in all these Avatars (incarnations), she also incarnates in a human form and joins the Lord in some such Avatars, and together as Lakshmi Narayana, they fight evil, establish righteousness and ensure the well-being of the people.
