Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vasuki had thousands of eyes and mouths. From his mouths he breathed smoke and blazing fire, which affected the demons, headed by Pauloma, Kaleya, Bali and Ilvala. Thus the demons, who appeared like sarala trees burned by a forest fire, gradually became powerless.
