Brahmā told this to Prajāpati; Prajāpati told it to Manu; Manu told it to the people. Having studied the Veda from the household of the teacher, according to the rule, having returned by completing the remainder of the teacher's service, living in a household in a pure place, engaged in self-study, establishing the righteous, having firmly placed all the senses within the self, not harming any beings except at the sacred bathing places, he lives thus, and for as long as his life lasts he attains the world of Brahman. He does not return again, he does not return again.
