iti navamaṃ brāhmaṇam ||1. This fire that is within a man and digests the food that is eaten, is Vaiśvānara. It emits this sound that one hears by stopping the ears thus. When a man is about to leave the body, he no more hears this sound.
Here is another meditation like the preceding ones. This fire is Vaiśvānara. Which fire? This that is within a man. Is it the element fire that is one of the components of the body? No, it is the one called Vaiśvānara, which digests the food. Which food? The food that is eaten by men. That is to say, the heat in the stomach. For direct sign of it the text says: As that fire digests the food, it emits this sound. What is it? That one hears by stopping the ears thus, with one’s fingers. The word ‘Etat’ is an adverb (meaning ‘thus’). One should meditate upon that fire as Vaiśvānara, or Virāj. Here too the result is identification with it. Incidentally a death omen is being described: (When a man, the experiencer in this body is about to leave the body, he no more hears this sound.
