Mahabharata — Shanti Parva, Shloka 26
महाभूत–इन्द्रिय–मनस्–बुद्धि–अन्तरात्मा विवेकः | Discrimination of Elements, Senses, Mind, Intellect, and Inner Self
त्रींश्वैवाग्नीन् यजेत् सम्यगात्मन्येवात्ममोक्षणात् | प्राणेभ्यो यजुष: पञ्च षट् प्राश्नीयादकुत्सयम्
trīṁś caivāgnīn yajet samyag ātmany evātma-mokṣaṇāt | prāṇebhyo yajuṣaḥ pañca ṣaṭ prāśnīyād akutsayam ||
毗耶娑说：“为求自我解脱，当于自身之内如法安立三圣火，在内而行供养。诵念《夜柔吠陀》中献给诸生命气息的仪轨真言时，先取五或六口为供献；随后不轻贱余食，默然而食。如此，以戒律维持内在之祭——‘气息火供’（prāṇa-agnihotra）——直至此身崩落。”

Educational Q&A
The verse teaches internalization of Vedic sacrifice: establish the ‘three fires’ within, offer the first mouthfuls to the vital breaths with Yajurvedic formulas, and then eat silently without criticizing the food—turning daily nourishment into disciplined spiritual practice aimed at liberation.
In Śānti Parva’s instruction on dharma and liberation, Vyāsa describes the form of ‘ātma-yajña’ (self-sacrifice): a householder/ascetic maintains an inward agnihotra by ritualized eating—first offering a few morsels to prāṇa through mantra, then consuming the rest with restraint and non-disparagement.
