catvāryetānyathotpādya tanumanyāṃ prajāpatiḥ /
rajastamomayīṃ rātrau jagṛhe kṣuttṛḍanvitaḥ //

Now after creating these four, the Prajāpati, feeling hunger and thirst, took another body composed of passion and darkness during the night; during its darkness the adorable unborn god created bearded monsters wasted with hunger; and they endeavoured to eat up that body. Some of those monsters, who said “let us preserve[5] it from them,” were called Rākṣasas in consequence; and those who said “let us devour[6] it” were called Takṣas, from yakṣaṇa, ‘eating,’[7] O brāhman.
