Jaiminīya Upaniṣad Brāhmaṇa 3.4

Now this uktha is sevenfold:
there are recited the stotriya, the anurūpa, the dhāyyā, the pragātha, the sūkta, the nivid, and the paridhānīyā.

This [earth] is the stotriya; Agni is the anurūpa; Vāyu is the dhāyyā; the intermediate space is the pragātha; heaven is the sūkta; the sun is the nivid—
therefore the Ṛgvedins recite the nivid when [the sun] has risen;
for the sun is the nivid—
the directions are the paridhānīyā. Thus pertaining to the deities.

Now pertaining to the self:
The self alone is the stotriya; offspring is the anurūpa; breath is the dhāyyā; mind is the pragātha; the head is the sūkta; the eye is the nivid; the ear is the paridhānīyā.

Some conclude it with a triṣṭubh, some with an anuṣṭubh.
One should indeed conclude it with a triṣṭubh.

Some recite [the uktha] after uttering these mystic utterances: "The great joined with the great [female]; the god joined with the goddess; the brahman joined with the brāhmaṇī."
Because [they say], "He joined, he joined."

Therefore now the bodies of a man are joined together;
for the man is this uktha.

"The great joined with the great [female]":
Agni is the great; this [earth] is the great [female].

"The god joined with the goddess":
Vāyu is the god; the intermediate space is the goddess.

"The brahman joined with the brāhmaṇī":
the sun is the brahman; heaven is the brāhmaṇī.

Of these deities, two deities together make nine syllables;
thus these worlds are ninefold-thrice (triṇava).

The brahman is threefold (trivṛt).
Having uttered that brahman, they recite.
This very stoma is that follower.

What they call this one single-stoma (ekastoma) is this one who purifies here [the wind].
This is pertaining to the deities.
Breath is pertaining to the self.
His body is the follower.

Just as a thread would be strung through a jewel—
[This is] the fourth khaṇḍa in the first anuvāka.
