I alone, having become the Vaiśvānara, the fire that stands in the belly, by the scripture 'this fire is the Vaiśvānara, the one within the person, by which this food is cooked' (Bṛhadāraṇyaka 5.9.1) and the like: being the Vaiśvānara, having resorted to, entered into, the body of breathing creatures, joined with the out-breath and the in-breath, I cook, I work the cooking of, food, eating, the four kinds of food, the eatable, the chewable, the suckable and the lickable. The enjoyer is the Vaiśvānara fire; the food to be enjoyed is the moon; for one who sees that this pair, fire and moon, is everything, there is no smearing of the fault of food. Further.

I, having become Vaishvanara, the belly-fire, resorting to the body of all living beings, joined with the difference of the workings of the in-breath and the out-breath, cook the fourfold food, of the form of the chewable, the suckable, the lickable, and the drinkable, eaten by them. Here the soma and Vaishvanara, which are glories of the supreme Person, are indicated in co-ordination with Him, 'having become the soma', 'having become Vaishvanara'. The Lord states the reason for the indicating of these two, and of the whole brood of beings, in co-ordination with the supreme Person.
