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.
