For when, in taking four times (butter with the sruva) in the guhû, he takes more butter, he thereby, in making the eater more limited, smaller, imparts vigour and strength to him. And when, in taking eight times in the upabhrit, he takes less butter, he thereby, in making that which (or, him who) is to be eaten more unlimited, more abundant, makes it (or, him) vigourless and weaker. And thus a king who has established himself among a numberless people, subdues them even from a single dwelling, and takes possession of whatever he likes: with that very same energy (the Adhvaryu acts) when he takes a greater quantity of butter in the guhû. Now what he takes in the guhû, that he offers with the guhû; and what he takes in the upabhrit, that also he offers with the guhû.
