Visnu is one of the three important gods of Indian religious belief, others being Brahma and Siva. His presence is found in the Rgveda where he is conceived to be all pervading lord. But with the theory of his incarnations, his importance increased. The Puranas, more particularly the Visnu and others, highlight his glory to a considerable extent. Some of the events like Samundramanthana (Churning of ocean), event of Gajendramoksa etc. are quite popular. One can find his temples throughout the country.
