The Great Epic of the Bhārata dynasty 1.58.1-2

1.58.1

janamejaya uvāca |
ya ete kīrtitā brahmanye cānye nānukīrtitāḥ |
samyaktāñśrotumicchāmi rājñaścānyānsuvarcasaḥ || 1 ||

"Janamejaya said, 'O Brahmana, those thou hast named and those thou hast not named, I wish to hear of them in detail, as also of other kings by thousands. And, O thou of great good fortune, it behoveth thee to tell me in full the object for which those Maharathas, equal unto the celestials themselves, were born on earth.'

1.58.2

yadarthamiha saṃbhūtā devakalpā mahārathāḥ |
bhuvi tanme mahābhāga samyagākhyātumarhasi || 2 ||
