tṛtīyametatkathitaṃ tava manvantaraṃ mayā /
tāmasasya caturthantu manorantaramucyate //

This third manvantara I have declared to thee. Now the fourth is called the period of Manu Tāmasa, who born of an animal’s womb illuminated the world with his fame; hearken to the birth of that Manu, as I tell thee, O brāhman. And the exploits of all those[11] Manus transcend the cognizance of the senses; and the birth of the high-souled Manus is to be known as such, and their majesty also.
