BG 10.28, Translation:

Of weapons I am the thunderbolt; among cows I am the surabhi. Of causes for procreation I am Kandarpa, the god of love, and of serpents I am Vāsuki.

BG 11.15, Purport:

Arjuna sees everything in the universe; therefore he sees Brahmā, who is the first creature in the universe, and the celestial serpent upon which the Garbhodakaśāyī Viṣṇu lies in the lower regions of the universe. This snake bed is called Vāsuki. There are also other snakes known as Vāsuki. Arjuna can see from the Garbhodakaśāyī Viṣṇu up to the topmost part of the universe on the lotus-flower planet where Brahmā, 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, Kṛṣṇa.

SB Canto 5

SB 5.24 Summary:

Below Sutala is the planet Talātala, the abode of the demon Maya. This demon is always materially happy because he is favored by Lord Śiva, but he cannot achieve spiritual happiness at any time. Below Talātala is the planet Mahātala, where there are many snakes with hundreds and thousands of hoods. Below Mahātala is Rasātala, and below that is Pātāla, where the serpent Vasukī lives with his associates.

SB 5.24.31, Translation:

Beneath Rasātala is another planetary system, known as Pātāla or Nāgaloka, where there are many demoniac serpents, the masters of Nāgaloka, such as Śaṅkha, Kulika, Mahāśaṅkha, Śveta, Dhanañjaya, Dhṛtarāṣṭra, Śaṅkhacūḍa, Kambala, Aśvatara and Devadatta. The chief among them is Vāsuki. They are all extremely angry, and they have many, many hoods—some snakes five hoods, some seven, some ten, others a hundred and others a thousand. These hoods are bedecked with valuable gems, and the light emanating from the gems illuminates the entire planetary system of bila-svarga.

SB Canto 6

SB 6.12.3, Translation:

Flying in the sky, Vṛtrāsura's trident resembled a brilliant meteor. Although the blazing weapon was difficult to look upon, King Indra, unafraid, cut it to pieces with his thunderbolt. Simultaneously, he cut off one of Vṛtrāsura's arms, which was as thick as the body of Vāsuki, the King of the serpents.
