Jaiminīya (Talavakāra) Brāhmaṇa 7.27.p1

7.27.p1

"That exhilarating drink of thine, which is choice..."
—thus for the Ārbhava Pavamāna[-stotra] the gāyatrī verses contain [the word] "exhilarating drink" (madvat).
Sap indeed is exhilarating drink.
Exhausted as it were is this third pressing.
Now, because these verses contain [the word] "exhilarating drink", they thus place sap in it; they swell it with this.
"With that, purify yourself as drink!"—thus they contain [the word] "drink" (andhasvat); food is indeed drink, for the attainment of food.
"Slayer of the hostile Vṛtra..."
—this is the form of the triṣṭubh.
For that which contains [the act of] slaying is the form of the triṣṭubh.
For the triṣṭubh is royal power.
"Associated, he became the ruddy one, with well-yielding cows..."
—rushing forth as it were from here is this day, because it is in bṛhatī form.
For yonder is the Bṛhat.
Now, in that it says "with well-yielding cows", it is for the approach (upasthiti) of the day itself.
