He who shines here is this agniṣṭoma; he is tied to the day.
They should conclude it together with the day; for he is indeed called 'tied to the day'.
They should proceed with it without haste, just as at the morning pressing, so at the midday pressing, so at the third pressing.
Thus indeed the sacrificer does not die prematurely.
Because they proceed here in the first two pressings without haste,
therefore here the eastern settlements are densely inhabited.
And because they proceed here in the third pressing with haste,
therefore here toward the west there are long wildernesses.
In that way the sacrificer would die prematurely.
Therefore they should proceed with it without haste,
just as at the morning pressing, so at the midday pressing, so at the third pressing.
Thus indeed the sacrificer does not die prematurely.
He should revolve after him with the recitation.
When he rises in the morning, then he shines gently:
therefore one should recite with a gentle voice at the morning pressing.
Then when he moves upward, then he shines more strongly:
therefore one should recite with a stronger voice at midday.
Then when he moves still further upward, then he shines strongest:
therefore one should recite with the strongest voice at the third pressing.
Thus one should recite if one has control of one's voice, for voice is the recitation.
With whatever progressively louder voice one is able to carry through to completion,
with that one should begin; this becomes best recited, as it were.
He indeed never sets and never rises.
When they think that he sets,
having reached the end of the day, he then turns himself around;
he makes night below and day on the other side.
And when they think that he rises in the morning,
having reached the end of the night, he then turns himself around;
he makes day below and night on the other side.
He indeed never sets.
He never sets;
he attains union, identity of form, and residence in the same world with him, who knows thus, who knows thus.
