vyāsa uvāca -
na jarā kṣupitpāsā vā na mṛtyurna bhayaṃ punaḥ |
na tu glāniḥ prabhavati brahmaloke sadānagha ||

Vyâsa said:-- “O King! The Brahmâloka is not touched by any vice nor sin; old age, hunger, thirst or fear of death nothing exists there; nor is there any other cause by which weariness comes. So what doubt there can be that the people there will be long-lived, free from old age and death! When the King S'aryâti went up to the Heavens, his sons were all destroyed by the Râksasas; those that remained, they, terrified left Kus'asthalî and fled on all sides. Vaivasvata Manu sneezed; owing to that, came out of his nose one powerful son; his name was Iksâku. He spread the Solar dynasty and became celebrated. Getting excellent initiation from the Maharsi Nârada, he began to meditate the Devî constantly and practised severe tapasyâ for the spread of his race. O King! Iksâku had one hundred sons; Vikuksi was the eldest; he was powerful and endowed with great strength. Iksâku became king and lived in Ayodhyâ. He sent his fifty sons, the powerful S'akuni and others to Uttarâpatha (Eastern) provinces for governing those countries. That high-souled monarch sent also other eight sons to govern the countries in the South. (Western). O King! He kept the remaining two sons by his side for his own service.”
Here ends the Eighth Chapter of the Seventh Book on the story of the King Revata and the spread of the Solar dynasty in the Mahâpuranam S'rî Mad Devî Bhâgavatam of 18,000 verses by Maharsi Veda Vyâsa.
