etatte kathitaṃ ṣaṣṭhaṃ mayā manvantaraṃ dvija /
cākṣuṣasya tathā janma caritañca mahātmanaḥ //

Thus I have narrated to thee the sixth manvantara, O brāhman, both the birth and the exploits of high-souled Cākṣuṣa. He who subsists at the present time is named Manu Vaivasvata; hear from me about the gods and other chief personages in his, the seventh, period.
