The Pravargya, indeed, is the Animal sacrifice, for the Animal sacrifice is everything, and the Pravargya is everything: when it (the meat) is put on the fire then it is the (Gharma) placed thereon; and when it is standing ready then it is the burning-hot (Gharma); and when it is offered then it is the overflowing (Gharma);--but, indeed, when the animal offering overflows all the gods and all beings subsist thereon; and, verily, the animal offering overflows for him who thus knows this.
