Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 15.4

That Marutvatīya hymn is an army-conquering divine hymn.

For by this Indra conquered armies.

In the middle of it he inserts the nivid.

Food is placed in the middle of the body.

Then he recites the nivids.

The nivids are the breath-prāṇas.

Thereby he places the breath-prāṇas in himself.

He recites them word by word, pausing [after each].

One by one, indeed, he thereby places the vital breaths in himself.

With the last [word], he pronounces the syllable oṃ.

Thereby he releases this very breath.

Therefore all vital breaths breathe along after this breath.

Moreover, they also say: 'The nivids are food.'

Therefore he should recite them with pauses.

For without haste, as it were, one eats food according to desire.

Having recited the uktha, he offers with: 'They who strengthened you in the slaying of Ahi, O Maghavan...'

...and with: 'They who [strengthened you] against Śambara, O possessor of bay steeds, they who in the search for cattle...'

With these, indeed, he performed these heroic deeds together.

Together with them is this drinking of soma of his.

It is a Triṣṭubh dedicated to Indra.

For the midday pressing belongs to Indra and has the Triṣṭubh [metre].

He makes the secondary vaṣaṭ-call, for the appeasement of the offerings;

for the establishment of the offerings.

Speech itself is that first Anuṣṭubh.

Five Gāyatrīs follow after it.

The invocation of Indra is the mind; the [hymn] to Bṛhaspati is the ear.

The out-breath, the in-breath, and the circulating breath are the three single verses.

The body is the hymn; that which is inside the body is the nivid.

The concluding verse is the foundation; the offering verse is food.
