tasmād ahar ahar viparyāsam anubrūyāt / (soma: upasadah)

therefore day by day in alternation should he repeat (hoping) ‘Let both symbols, both desires be attained.’ He should repeat without taking breath, for the continuity of the breaths; for continuous as it were are these breaths. Thrice each one should he repeat; these worlds are three; verily thus he obtains these worlds. They repeated together make up nine; the seasons are six; these worlds are three; verily thus they make up that. He should not say this Nigada in the kindling verses; the Nigadas are omitted; it would be repetition if one were to say this Nigada. ‘He should not invite at all,’ some say; ‘But how without inviting can he say the offering verse for a deity?’ (For this reason). After the Ṛc he should invite with (the invitatory verses), ‘Bring Agni, bring Soma, bring Viṣṇu.’ For these three gods he says the offering verses; these worlds are three; verily thus he makes these worlds full of light.
