About Vishnu
Vishnu, also known as Narayana and Hari, is one of the principal deities of Hinduism. He is the Supreme Being within Vaishnavism, one of the major traditions within contemporary Hinduism, and the god of preservation (sattva). Though not prominently represented in the Vedas Vishnu was possibly already a significant non-elite divine figure in early Vedic times. Vishnu rose to prominence in post-Vedic times, and was identified with various local traditions and deities, particularly the Bhāgavata-deities Vāsudeva-Krishna and Gopala-Krishna and the Pāñcarātra-deity Narayana, in the last centuries BCE and the early centuries CE.
