Within that palace, Arjuna and Krishna saw Lord Maha-Vishnu lying very comfortably on the very soft, white body of Sesa Naga, a great serpent with thousands of hoods, each one of them decorated with valuable, effulgent jewels. Lord Maha-Vishnu appeared all-pervading and very powerful, and Arjuna could understand that the Supreme Personality of Godhead in that form is known as Purusottama, the supreme or best Personality of Godhead.
