' Thus solicited, the sage Dadhichi, who was a great Yogin and who regarded happiness and misery in the same light, without being at all cheerless, concentrated his Soul by his Yoga power and cast off his body. When his Soul left its temporary tenement of clay, Dhatri, taking his bones, created an irresistible weapon called the Thunder-bolt. With the Thunder-bolt thus made with the bones of a Brahmana, which was impenetrable by other weapons and irresistible and pervaded by the energy of Vishnu, Indra struck Viswarupa the son of Tashtri. Having slain the son of Tashtri thus, Indra severed his head from the body. From the lifeless body, however, of Viswarupa, when it was pressed, the energy that was still residing in it gave birth to a mighty Asura of the name of Vritra. Vritra became the foe of Indra, but Indra slew him also with the Thunder-bolt. In consequence of the sin of Brahmanicide, being thus doubled Indra became overcome with a great fear and as the consequence thereof he had to abandon the sovereignty of heaven. He entered a cool lotus stalk that grew in the Manas lake. In consequence of the Yoga attribute of Anima, he became very minute and entered the fibres of that lotus stalk.[1860] When the lord of the three worlds, the husband of Sachi, had thus disappeared from sight through fear of the sin of Brahmanicide, the universe became lordless. The attributes of Rajas and Tamas assailed the deities. The Mantras uttered by the great Rishis lost all efficacy. Rakshasas appeared everywhere. The Vedas were about to disappear. The inhabitants of all the worlds, being destitute of a king, lost their strength and began to fall an easy prey to Rakshasas and other evil Beings. Then the deities and the Rishis, uniting together, made Nahusha, the son of Ayusha, the king of the three worlds and duly crowned him as such. Nahusha had on his forehead full five-hundred luminaries of blazing effulgence, which had the virtue of despoiling every creature of energy.
