Abhaya-Itihāsa: Karma, Indriyas, and the Non-sensory Brahman
Brāhmaṇī–Brāhmaṇa Saṃvāda
तेषामन्योन्यभक्षाणां सर्वेषां देहचारिणाम् । अनिनिर्वेश्वानरो मध्ये सप्तधा दीव्यतेडन्तरा
teṣām anyonyabhakṣāṇāṁ sarveṣāṁ dehacāriṇām | aninirveśvānaro madhye saptadhā dīvyate ’ntarā ||
伐由说道：“在诸生命之气之中——彼此相资相持，遍行一切众生之身——中央之域有毗湿婆那罗火（Vaiśvānara）安住。它处于中枢（脐轮之处，为萨玛那之座），此内火以七种不同形相辉耀。”

Educational Q&A
The verse teaches an inner-physiological and yogic ethic: life is sustained by interdependent vital forces (prāṇas), and at their center the Vaiśvānara fire—digestive/metabolic intelligence—operates as a sevenfold radiance. It frames bodily life as an ordered, sacred system where balance (especially of Samāna at the navel) supports health, restraint, and disciplined living.
Vāyudeva is explaining the internal functioning of the vital airs within embodied beings. He describes how the prāṇas support one another and how, in their central locus, the Vaiśvānara fire shines sevenfold—linking bodily processes to a broader dharmic and cosmological understanding.
