Jaiminīya (Talavakāra) Brāhmaṇa 2-8.430

Then, that [night] when they dwell having undertaken the Viṣuvant, they dwell in Āditya itself. Thereby they secure whatever food is in Āditya. And they know: 'We are now in Āditya; of us there is no misfortune whatsoever.'
Then, that [night] when they dwell having undertaken the Viśvajit, they dwell in Indra itself. Thereby they secure whatever food is in Indra. And they know: 'We are now in Indra; of us there is no misfortune whatsoever.'
Then, that [night] when they dwell having undertaken the Go and Āyus [days], they dwell in day and night themselves. Thereby they secure whatever food is in day and night. And they know: 'We are now in day and night; of us there is no misfortune whatsoever.'
Then, that [night] when they dwell having undertaken the days of the twelve-day rite, they dwell in the worlds themselves. Thereby they secure whatever food is in the worlds. And they know: 'We are now in the worlds; of us there is no misfortune whatsoever.'
Then, that [night] when they dwell having undertaken the Mahāvrata day, they dwell in Prajāpati itself. Thereby they secure whatever food is in Prajāpati. And they know: 'We are now in Prajāpati; of us there is no misfortune whatsoever.'
Then, that [night] when they dwell having undertaken the concluding Atirātra, they dwell in that world. Thereby they secure whatever food is in that world. And they know: 'We are now in that world; of us there is no misfortune whatsoever.'

Some are indeed sitters in the real; others are sitters in the sacrificial session.

Some sit in the real itself; others sit in the sacrificial session.

Those who undergo consecration knowing thus are truly the sitters in the real.

For they proceed sitting in these deities as the real.

They indeed strike away all evil.

Now, those who wander about with their tufts cut off, seeking handouts—they are the sitters in the sacrificial session.

If one reviles him who knows thus, as if he might incur these deities, [saying,] 'It is not so'—for he reviles him who has taken refuge in these

deities, who is dwelling in them—he who knows thus has no misfortune whatsoever.

[He has no misfortune] who knows thus.

He who reviles him, he incurs misfortune.

These are indeed just the ten days of the year: the two Atirātras, the Ārambhaṇīya and Mahāvrata

days, the Pṛṣṭhya and Abhiplava, the Viśvajit and Abhijit, the Svarasāmans, and the Viṣuvant.

Pravati Kauśānteya was a Vedic student of Kusurbinda Auddālaki.

He said to him: 'Dear boy, son of a charioteer, how many days of the year did your father reckon?'

'Ten,' he said.

'Ten indeed,' he said. 'The Virāj has ten syllables; the Virāj is food; the sacrifice is of the nature of the Virāj.'

'How many [else] did he reckon?'

'Nine,' he said.

'Nine indeed,' he said.

'There are nine vital breaths in a person.

And the sacrifice is extended by the vital breaths.'

'How many [else] did he reckon?'

'Eight,' he said.

'Eight indeed,' he said.

'The Gāyatrī has eight syllables.

The sacrifice is of the nature of the Gāyatrī.'

'How many [else] did he reckon?'

'Seven,' he said.

'Seven indeed,' he said.

'There are seven meters; the sacrifice is extended by the meters.'

'How many [else] did he reckon?'

'Six,' he said.

'Six indeed,' he said.

'The year consists of six seasons.

The year is the sacrifice.'

'How many [else] did he reckon?'

'Five,' he said.

'Five indeed,' he said.

'The sacrifice is fivefold.

Cattle are fivefold.'

The cattle are the sacrifice.

"How many did he consider?"

"Four," he said.

"Indeed four," he said.

"Four are the quarters, four-footed are the cattle, four are the meters that bear the sacrifice: the Gāyatrī,

the Triṣṭubh, the Jagatī, the Anuṣṭubh."

"How many did he consider?"

"Three," he said.

"Indeed three," he said.

"The sacrifice has three pressings; there are three [breaths]: in-breath, out-breath, and diffused breath; these worlds are three."

"How many did he consider?"

"Two," he said.
