Five actions of fire in the body are named, and all five are verbs describing what happens to food: it releases, fills, dries, burns, floods. This is a description of digestion, and a material one. Indian body-science calls this jāṭhara-agni, "the stomach fire," and its whole structure rests on the thought that food is not simply lodged in the body but digested by fire — that is, transformed, not merely transported.
This thought is correct in substance and was voiced long before gastric juice and enzymes were distinguished. What is eaten indeed does not pass into the body as it is: it breaks down and is reassembled; and to call this process fire was, for the ancient observer, a precise solution. The Vaiṣṇava side names this same fire and speaks of it in the Gītā's famous verse: "I, having become the fire Vaiśvānara, abide in the body of living beings, and, joined with the in-breath and out-breath, digest the fourfold food" (15.14).
This verse is worth remembering, for it shows what the dispute is really about. Everything named here as powers and deities is there named His action; and the difference is not in the observation but in whom it is attributed to. Digestion is the same in both; but it is one thing to say "a fire works in me," and another to say "He works in me."
