Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Arjuna said: My dear Lord Krishna, I see assembled 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 all the sages and divine serpents.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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 Garbhodaka-sayi 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 Garbhodaka-sayi 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, who was sitting in one place on his chariot. This was possible by the grace of the Supreme Lord, Krishna.
