Bhagavad Gita 15.14
अहं वैश्वानरो भूत्वा प्राणिनां देहमाश्रितः । प्राणापानसमायुक्तः पचाम्यन्नं चतुर्विधम् ॥
ahaṁ vaiśvānaro bhūtvā prāṇināṁ deham āśritaḥ | prāṇāpāna-samāyuktaḥ pacāmy annaṁ catur-vidham ||
Translation
Becoming the digestive fire abiding in the bodies of breathing beings, joined with the in-breath and out-breath, I digest the fourfold food.
Reflection
What changes when belly-warmth is noticed as a hosted presence rather than a function?
Read this verse in its chapter: Chapter Fifteen
Krishna localises further. Vaishvanara is the digestive fire seated in the belly of every breathing creature. He sits there in person. With prana, the in-breath, and apana, the out-breath, working as bellows, the meal gets cooked into four kinds: chewed, sucked, licked, drunk. Verse refuses to leave the cosmos out at arm's length. Hunger is not a private affair. Digestion is not a private affair. The presiding heat metabolising lunch right now is a divine kitchen-fire. Beginner practice: notice next belly-warmth after eating, and let one breath cycle land with the line, vaishvanaro bhutva. Body remembers it is hosting.
