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.
Behold in calm waters the Lotus blooms In the stillness of self, the God-Flower shines Holy in Stillness. The mind becomes subtle and perceives the all-vision In the simplest of forms.... Art by Kim Attwooll
While Krishna was playing with some herdboys, their ball fell into the river and Krishna jumped after it. The serpent Kāliya rose up with his hundred and ten hoods vomiting poison and wrapped himself around Krishna's body. Krishna became so huge that Kāliya had to release him. When he saw the Brij folk were afraid he sprang onto Kāliya's head and assumed the weight of the whole universe, and danced on the naga's heads, beating time with his feet.
