Jaiminīya (Talavakāra) Brāhmaṇa 2-8.340

Now, these stomas are Jyotis, Gauḥ, and Āyus. / These, indeed, are the propitious, peaceful, right-path stomas: namely Jyotis, Gauḥ, and Āyus. / Thinking, 'Those stomas which are propitious, peaceful, and of the right path, by them let it not be un-praised,' [they perform them]. / And they amount to the Virāj. / Thereby they take hold of the Virāj as food. / If someone mounts upon a superior without an agreement, he certainly injures him; by whatever misfortune he desires, into that he leads him. / But he who mounts upon him following an agreement, having approached him by agreement, he does not injure him. / In that these stomas are Jyotis, Gauḥ, and Āyus, it is just as if one were to mount upon a superior following an agreement, having approached him by agreement. / Now, this Agniṣṭoma is the threefold Agniṣṭut. / The threefold [stoma], indeed, is the priesthood. / The pṛṣṭha six-day rite is the nobility. / In that they undertake the Agniṣṭut before the pṛṣṭha six-day rite, he places the priesthood in front of the nobility; / therefore a Brahmin is the domestic priest of a Kṣatriya. / And by one sacrificial session they undertake two sacrificial sessions: the twelve-day rite and the fifteen-night rite. / The concluding Atirātra is sacred to Vaiśvānara; for non-soma-sacrificial periods have their conclusion in Vaiśvānara.

This sacrificial session indeed belongs to two months.

The prosperity through that is precisely this prosperity.

What two months indeed are, that is the prosperity of a season.

And a season is visibly the prosperity of the year.

It is the year that they wish to obtain, the year they desire to attain, when they sacrifice, when they sit for a sacrificial session.

For there is nothing whatsoever outside the year.

Autonomous rule, indeed, are these nights which are twenty-one: ten days on that side, ten on this side.

Now, the day which is in the middle, that is the autonomous ruler, that is the heavenly world.

Thus they go to the zenith of the sun, thus they go to autonomous rule.

Thus they become not following behind another.

Now, these nights amount precisely to the Virāj.

Thereby they attain lordship and sovereign rule over the food of the Virāj.

And there are five, and there is the Virāj.

Those five divine envelopes that exist—this is their prosperity.

Whatever sacrifice is fivefold, whatever cattle are fivefold, whatever food is fivefold, the five seasons that exist, and whatever is in groups of five—

of all that, this is the prosperity, of that the attainment.

Ten are these days on that side, ten on this side, the central day (viṣuvat) is the twenty-first.
