Jaiminīya (Talavakāra) Brāhmaṇa 2-7.199

'Adha kṣapā pariṣkṛtaḥ'—[the hymn] ends with an anuṣṭubh.
Truly, that Udgātṛ should officiate as sacrificing priest for a king with the Rājasūya, who would make him mount the divine throne of the gods at the very Bahiṣpavamāna.
The introductory verse is an anuṣṭubh; the final one is an anuṣṭubh.
Of those two there are sixty-four syllables.
Of those, the sixty [syllables] are the throne;
then the four [syllables] are the legs of the throne.
In this way, indeed, the Udgātṛ makes the king mount the divine throne of the gods at the very Bahiṣpavamāna.
The ājya [stotras] are of both kinds;
for two sāmans are performed here.
Regarding this they say: only one of the two kinds should be performed, namely the Bārhatas;
for the ājyas belong to the subject: 'May the kṣatra be consecrated through the powerful subject,' [they think].
Now they also say: both kinds must be performed;
for being consecrated, he is consecrated for the sovereignty of all;
therefore both kinds should indeed be performed.
They are fifteen-versed;
the fifteen-fold is the kṣatra;
'May he be consecrated by the kṣatra,' [he thinks].

For him who has emerged from the purificatory bath, he fastens on a wreath of twelve lotus blossoms.

The waters, indeed, were the wives of the gods.

They desired pairing.

The gods approached them.

They conceived an embryo.

From that the lotus blossoms were born.

The waters are truth.

The consecration is truth.

The lotus blossoms are the truth of truth itself.

With the truth of truth itself he fastens on him the heat [of asceticism] and consecration.

It has twelve lotus blossoms.

Twelve months are the year.

The year is the sacrifice.

The sacrifice itself he thereby fastens onto him.

Moreover, they say: it should have seven lotus blossoms.

Seven are the meters.

By the meters the sacrifice is extended.

The sacrifice itself he thereby fastens onto him.

Moreover, they say: it should have six lotus blossoms.

Six seasons are the year.
