Vyâsa said:-- O King! Thus cursed, the King Nahusa began to chant hymns to that best of the Munis, and, while praising, fell from the Heavens and instantly turned into a snake. Brihaspatî, then, quickly went to the Mânasarovara Lake and informed Indra everything in detail. Indra became very glad on hearing in detail of the downfall of the King Nahusa from Heaven and remained there gladly. When the Devas and Munis saw this downfall into the earth of Nahusa, they all went to the Lake Mânasarovara where Indra was staying. They then all encouraged Indra and honoured him by bringing him back to the Heavens. All the Devas and Risis installed Indra on the throne and then performed the Inauguration ceremony of the all auspicious Devî. On getting back his own throne. Indra, too, began to sport in the beautiful Nandana Garden with his dear consort S'achî, in the home of the Devas. Vyâsa said:-- O King! Indra had to suffer such severe hardships on account of his slaying the Maharsi Vis'varûpa, the Lord of the Asuras. Subsequently through the grace of the Devî, he got back his own seat. O King! Thus I have narrated before you to my best, this excellent story of the killing of Vritrâsura and thus have answered your question. O Ornament of the Kuru family! The fruits will be exactly according to the Karma done. The effects of the Karma done must be borne whether they be auspicious or inauspicious. (So Indra had to suffer for his Karma, the killing of a Brâhmana.)
Here ends the Ninth Chapter of the Sixth Book on Indra's getting the fruits of his killing a Brâhmana and on the downfall of the King Nahusa from the Heavens in the Mahâpurânam S'rî Mad Devî Bhâgavatam of 18,000 verses by Maharsi Veda Vyâsa.
