āhūya tūṣṇīṃśaṃsaṃ śaṃsati, retas tat siktam vikaroti.
siktir vā agre 'tha vikṛtir
upāṃśu tūṣṇīṃśaṃsaṃ śaṃsaty, upāṃśv iva vai retasaḥ siktis
tira iva tūṣṇīṃśaṃsaṃ śaṃsati, tira iva vai retāṃsi vikriyante

ii. 39 (x. 7). After the call, he recites the silent praise; thus he develops the seed poured; first is then pouring, then development. Inaudibly he recites the silent praise; inaudible as it were is the pouring of seed. Secretly as it were he recites the silent praise; secretly as it were are seeds developed. Of six sentences he recites the silent praise; sixfold is man, with six members; verily thus he develops the self as sixfold and of six members. Having recited the silent praise he recites the Puroruc; thus he propagates the seed when developed; first there is development, then birth. Aloud he recites the Puroruc, verily openly he propagates him. He recites the Puroruc in twelve sentences; the year has twelve months; Prajāpati is the year; he is the propagator of all this. He who is the propagator of all this propagates him with offspring and cattle, for generation. He is propagated with offspring, with cattle, who knows thus. He recites the Puroruc to Jātavedas, with an allusion to Jātavedas. They say, 'Since the morning pressing is the abode of Jātavedas, then why at the morning pressing does he recite a Puroruc to Jātavedas?' Jātavedas is the breath, for he knows of born creatures. Of so many creatures as he knows, they become; for how could they exist of whom he knows not? If one knows the making of the self in the Ājya, that is well known.
