Mahabharata Anushasna Parva Chapter 99:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 99:2 Agastya said, 'How can I succeed in cursing Nahusha, O great Rishi? It is known to thee how the boon-giving (Brahman) himself has given Nahusha the best of boons! Coming to heaven, the boon that Nahusha solicited was that whoever would come within the range of his vision would, deprived of all energy, come within his sway. The self-born Brahman granted him even this boon, and it is for that reason that neither thyself nor I have been able to consume him. Without doubt, it is for this reason that none else amongst the foremost of Rishis has been able to consume or hurl him down from his high position. Formerly, O Lord, nectar was given by Brahman to Nahusha for quaffing. For that reason also we have become powerless against him. The supreme deity, it seems, gave that boon to Nahusha for plunging all creatures into grief. That wretch among men behaves most unrighteously towards the Brahmanas. O foremost of all speakers, do thou tell us what should be done in view of the situation. Without doubt, I shall do what thou wilt advise.' Bhrigu said, 'It is at the command of the Grandsire that I have come to thee with the view of counteracting the puissance of Nahusha who is possessed of great energy but who has been stupefied by fate. That exceedingly wicked-souled wight who has become the chief of the deities will today yoke thee to his car. With the aid of my energy I shall today hurl him down from his position as Indra in consequence of his having transcended all restraints! I shall today, in thy very sight, re-establish the true Indra in his position—him, viz., who has performed a hundred horse-sacrifices,—having hurled the wicked-souled and sinful Nahusha from that seat! That unrighteous chief of the deities will today insult thee by a kick, in consequence of his understanding being afflicted by fate and for bringing about his own downfall. Incensed at such an insult I shall today curse that sinful wretch, that enemy of the Brahmanas, that has transcended all restraints, saying, "Be thou transformed into a snake!" In thy very sight, O great ascetic, I shall today hurl down on the earth the wicked-souled Nahusha who shall be deprived of all energy in consequence of the cries of "Fie" that will be uttered from all sides.[] Verily, I shall hurl down Nahusha today, that wight of unrighteous deeds, who has, besides, been stupefied by lordship and power. I shall do this, if it be acceptable to thee, O ascetic!' Thus addressed by Bhrigu, Mitravaruna's son Agastya of unfading puissance and glory, became highly gratified and freed from every anxiety.
