1.176

Thus he does not become rough. / Now former Brahmins used to consider this: 'Who indeed would cross beyond the open jaws of the dolphin?' / This Yajñāyajñīya stands facing upstream with open jaws at the single path. / He passes safely beyond her having covered [her jaws] with food from her mouth: / 'The nourisher, we, the immortal, Jātavedas…' / If he should say: 'pra pra vayam', the sacrificer would be liable to die. / But when he says: 'poprim', this becomes a nourisher for him. / 'hiṃ māyi dāyivam'— / If he should say: 'dāsam', the sacrificer would become a slave. / But when he says: 'dāyivam'—for they say: 'The fully praised sacrifice is to be made to go to heaven'— / it is to heaven that they make the fully praised sacrifice go. / 'I would praise the dear friend now'— / If he should say: 'I would not praise the dear friend', he would not praise the dear friend. / But when he says: 'I would praise the dear friend now', he praises the dear friend.
