Pragâpati said to him, 'My boy, why criest thou, when thou art born out of labour and trouble?' He said, 'Nay, but I am not freed from (guarded against) evil; I have no name given me: give me a name!' Hence one should give a name to the boy that is born, for thereby one frees him from evil;--even a second, even a third (name), for thereby one frees him from evil time after time.
