Now, they censure this in that they regard it merely as a sacrificial session (sattra); formerly they indeed approached this as a sattra. But by this [distinction] the stomas pertaining to a sattra and those accompanied by sacrificial gifts are discerned: those having an Atirātra at both ends are sattra rites; those having an Atirātra at one end are accompanied by sacrificial gifts. If one should sacrifice with this accompanied by sacrificial gifts, he should sacrifice having performed an Agniṣṭoma beforehand. Now, for that rite which has the stomas of the Pṛṣṭhya-six-day rite, the Mahāvrata on the fifth day, and an Atirātra with the Viśvajit stoma: right here and now, indeed, those who sacrifice, who sit at a sattra, disperse speech. They bring it to completion by the tenth day alone, [thinking], 'Let the Mahāvrata be approached when speech has been completed, not dragged apart, and established.' Food indeed is the Mahāvrata, for the attainment of food alone. The Atirātra has the Viśvajit stoma; this is, as it were, turned away. The Atirātra with the Viśvajit stoma is aimed directly at the heavenly world; turned away, he goes to the heavenly world by means of it. And as the fourth stoma is the twenty-one-fold (ekaviṃśa)—and the twenty-one-fold is a support—he supports himself firmly on this [earth] through it.
