Vishnu is considered the preserver of the universe. Some believe that he has been incarnated nine times, and will be reincarnated once more at the end of the world. Those who follow the Vaishnava tradition of Hinduism regard him as the supreme god. He is often associated with light and the Sun. He is generally represented as a four-armed, blue-skinned human. His four arms hold the conch, the chakra, the lotus, and the mace. His consort is Lakshmi.
"You are the original lamp. Other incarnations may possess the same candle power as the original lamp but the original lamp is the beginning of all light" Lord Brahma, in "Prayers Offered by Lord Brahma to Lord Krsna," #KRSNA BOOK, Chapter 14
