28.10

yāvattu nopanayanaṃ kriyate vai dvijanmanaḥ /
kāmaceṣṭoktibhakṣyaśca tāvad bhavati putraka //

“Hear also the connexions among the four periods of a brāhman’s life. A man who has not erred from the duty of his own class gains perfect felicity: he goes to hell after death, if he has served what is forbidden. And as long indeed as a dvija is not invested with the sacred thread, so long, my son, he acts, speaks and eats unrestrainedly.
