c8.104

The Divine Lord Fire (bhagavān Agnir īśvaraḥ) abides in the belly, cooks the food and extracts its essence. Owing to the extreme subtleness of his nature, he cannot be watched while at work. He is guarded and blown upon by three winds, “blowing forward” (prāṇa), “blowing downward” (apāna), and “blowing together” (samāna), each of which abides in its own place.
