tadvatse brūhi vatsaṃ svaṃ kumāraṃ vṛddhasaṃmatam |
mamādya tvaṃ sabhṛtyasya mokṣārthaṃ vedavittamam || 26 ||

Sauti continued, 'Thus encouraged by him, that best of snakes began to dwell in Indra's abode in joy and happiness. But Vasuki, seeing that the snakes were incessantly falling into the fire and that his family was reduced to only a few, became exceedingly sorry. And the king of the snakes was afflicted with great grief, and his heart was about to break. And summoning his sister, he spake unto her, saying, 'O amiable one, my limbs are burning and I no longer see the points of the heavens. I am about to fall down from loss of consciousness. My mind is turning, my sight is falling and my heart is breaking. Benumbed, I may fall today into that blazing fire! This sacrifice of the son of Parikshit is for the extermination of our race. It is evident I also shall have to go to the abode of the king of the dead. The time is come, O my sister, on account of which thou wert bestowed by me on Jaratkaru to protect us with our relatives. O best of the women of the snake race, Astika will put an end to the sacrifice that is going on. The Grandsire told me this of old. Therefore, O child, solicit thy dear son who is fully conversant with the Vedas and regarded even by the old, for the protection of myself and also of those dependent on me."'
