Mahabharata Udyoga Parva Chapter 16:2

Mahabharata Udyoga Parva Chapter 16:2 Indra said, "How hath Nahusha obtained the throne of heaven, difficult to get? What austerities did he practise? How great is his power, O Vrihaspati! Vrihaspati said, "The gods having been frightened, wished for a king of heaven, for thou hadst given up the high dignity of heaven's ruler. Then the gods, the Pitris of the universe, the saints, and the principal Gandharvas, all met together, O Indra, and went to Nahusha and said, 'Be thou our king, and the defender of the Universe!' To them said Nahusha, 'I am not able; fill me with your power and with the virtue of your austerities!' So told, the deities strengthened him, O king of the gods! And thereupon Nahusha became a person of terrible strength, and becoming thus the ruler of the three worlds, he hath put the great saints in harness, and the wretch is thus journeying from world to world. Mayst thou never see Nahusha who is terrible. He emitteth poison from his eyes, and absorbeth the energy of all. All the gods are exceedingly frightened; they go about concealed and do not cast a glance at him! Salya continued, 'While that best of Angira's race was thus speaking, there came that guardian of the world, Kuvera, and also Yama the son of Surya, and the old god Soma, and Varuna. And arrived there they said to the great Indra, "How lucky that the son of Twashtri hath been killed, and Vritra also! How lucky, O Indra, that we are beholding thee safe and sound, while all thy enemies have been killed!" Indra received all those guardians of the worlds, and with a glad heart greeted them in proper form with a view to requesting them in connection with Nahusha. And he said, Nahusha of terrible mien is the king of the gods; therein lend me your assistance." They replied, "Nahusha is of awful mien; his sight is poison; we are afraid of him, O God. If thou overthrowest Nahusha, then we shall be entitled to our shares of sacrificial offerings, O Indra." Indra said, "Let it be so. You and the ruler of the waters, and Yama, and Kuvera shall this day be crowned along with me. Aided by all the gods, let us overthrow the foe Nahusha of terrible gaze." Then Agni also said to Indra, "Give me a share in sacrificial offerings. I also shall lend you my assistance." Indra said to him, "O Agni, thou also shalt get a share in great sacrifices,—there will be a single share (in such) for both Indra and Agni. Salya continued, 'Thus did the illustrious lord Indra, the chastiser of Paka, the giver of boons, bestow, after deliberation upon Kuvera the sovereignty over the Yakshas, and all the wealth of the world; upon Yama, the sovereignty over the Pitris; and upon Varuna, that over the waters.
