1.70.2

yādavānāmimaṃ vaṃśaṃ pauravāṇāṃ ca sarvaśaḥ |
tathaiva bhāratānāṃ ca puṇyaṃ svastyayanaṃ mahat |
dhanyaṃ yaśasyamāyuṣyaṃ kīrtayiṣyāmi te'nagha || 2 ||

"Vaisampayana said, 'Hear now, as I recite the recorded genealogy, that is sacred and subservient to religion, profit and pleasure, of these royal sages--Daksha, the lord of creation, Manu, the son of Surya, Bharata, Ruru, Puru, and Ajamidha. I shall also recite to thee, O sinless one, the genealogies of the Yadavas and of the Kurus and of the king of the Bharata line. These genealogies are sacred and their recitation is a great act of propitiation. That recitation conferreth wealth, fame and long life. And, O sinless one, all these I have named shone in their splendour and were equal unto the great Rishis in energy.
