Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 6.9

'Indra is the mightiest and strongest of the gods; bring it to him.'

They brought it to him.

He appeased it with the holy power.

Therefore one says, 'Indra is the brahman.'

He gazes upon it, saying, 'With the eye of Mitra I gaze upon you.'

With the eye of Mitra indeed he thereby appeases it.

Then he receives it, saying, 'At the impulse of god Savitṛ, with the arms of the Aśvins, with the hands of Pūṣan, I receive you.'

With these deities indeed he thereby appeases it.

Having pushed aside the grass, he places it on the bare ground with the handle pointing east, saying, 'On the navel of the earth I place you, in the lap of Aditi.'

The earth indeed is the appeaser of foods.

He thereby appeases it.

Taking it from there, he eats it, saying, 'With the mouth of Agni I eat you.'

Agni indeed is the appeaser of foods.

He thereby appeases it.

Then he sips water after it, saying, 'Peace are you.'

Water indeed is peace and medicine.

Peace indeed, medicine, is thereby produced in the sacrifice.

Then he touches his vital breaths.

Whatever of the vital breaths has here been wounded or injured, that he thereby restores, that he heals.

Finally he touches his navel, saying, 'In the belly of Indra I place you.'

For Indra indeed appeased it.

Now, as to the fact that he impels with the whisper addressed to Savitṛ,

Savitṛ is the impeller, for the impelling of the ritual act.

Prajāpati created the sacrifice.

By the establishment of the sacred fires alone he emitted the seed.

With the Agnihotra, [he created] gods, humans, and asuras.

With the New and Full Moon sacrifices, he created Indra.

For them he created this food and drink:

these oblation-sacrifices and the Soma sacrifice.

Then, whatever desire they desired, that they obtained by these courses.

[They obtained] food and nourishment by the Āgrayaṇa.

Regarding this they say: 'Why are they called courses (ayana)?'

They are indeed attainments (gamana) of every desire and of the heavenly world.
