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.
There is an ocean at the bottom of each material universe. A huge form of Vishnu reclines on Sesha Naga, an expansion of Himself. His wife Laxmi, also part of Him, massages His feet. From Vishnu (goodness) comes Brahma who begins creation (passion) within the universe. Each universe also has a Shiva, part of Vishnu combined with matter (ignorance), allowing those who live in that mode to worship God. OM, the sound of Vishnu's conch shell, is shown by Sesha Naga's form.
