'Forward the wise somas; forward, o soma, to the feast of the gods;'
'Run forward, sit down around the tub'—
thus there are [verses] containing 'forward' (pra) on the Rathantara day.
This day is indeed to be led forward.
'Forward' (pra) is the form of the Gāyatrī.
With the form of the Gāyatrī they go forward.
That it has five sāmans is irregular, unprosperous.
Out-breath, in-breath, diffused breath—that is the triplet.
They cut that apart.
Self, offspring, wife, these worlds—they cut that apart.
There are three sāmans.
That is prepared: ninefold, having three sāmans.
Then the Āśva, with the word-finale, without stobha, is connected with the Rathantara.
Therefore it is performed on the Rathantara day.
The purifying [soma], rich in iḷā, is performed with the Somasāman.
A five-sāman [day] is truly fit to encompass the year.
Therefore, that the Yaudhājaya has a six-syllable finale, [it is because] there are six seasons, for the yoking of the year.
'Unto the vats, the brown ones'—
thus there is 'unto' (abhi), which is the form of the Rathantara.
This day is connected with the Rathantara.
'Pressed for Indra, Vāyu, Varuṇa, the Maruts'—
thus there are [verses] containing 'Maruts' (marutvat-).
Containing 'Maruts' is the form of the midday.
From that form of the midday they do not depart.
On them the Gāyatra has its Brāhmaṇa explained.
