He offers [for] twelve days.
Forty-eight oblations are made up.
The jagatī indeed has forty-eight syllables.
The Ādityas are forty-eight gods.
They are attached to the jagatī.
For those Āditya gods, the jagatī yields desires, whatever they desire, syllable by syllable.
In the same way it yields [them] for him who offers.
He wins the jagatī among meters, the Ādityas among the gods.
He ascends to union, to sharing the same world, with the Āditya gods—he who, knowing thus, offers the fire-offering.
