Arjuna said: My dear Lord Krsna, I see assembled together in Your body all the demigods and various other living entities. I see Brahma sitting on the lotus flower as well as Lord Siva and many sages and divine serpents.
Arjuna sees everything in the universe; therefore he sees Brahma, who is the first creature in the universe, and the celestial serpent upon which the Garbhodakasayi Visnu lies in the lower regions of the universe. This snake bed is called Vasuki. There are also other snakes known as Vasuki. Arjuna can see from the Garbhodakasayi Visnu up to the topmost part of the universe on the lotus-flower planet where Brahma, the first creature of the universe, resides. That means that from the beginning to the end, everything could be seen by Arjuna sitting in one place on his chariot. This was possible by the grace of the Supreme Lord, Krsna.
