Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Beneath Rasatala is another planetary system, known as Patala or Nagaloka, where there are many demoniac serpents, the masters of Nagaloka, such as Sankha, Kulika, Mahasankha, Sveta, Dhanañjaya, Dhrtarastra, Sankhacuda, Kambala, Asvatara and Devadatta. The chief among them is Vasuki. 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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thus end the Bhaktivedanta purports of the Fifth Canto, Twenty-fourth Chapter, of Srimad-Bhagavatam, entitled “The Subterranean Heavenly Planets.”
