apānaprāṇayor madhye prāṇāpānasamāhitaḥ | samanvitastv adhiṣṭhānaṃ samyak pacati pāvakaḥ ||
婆罗堕阇说道：在阿婆那（apāna）与普拉那（prāṇa）之间——即脐轮之处——消化之火依凭并调和于普拉那与阿婆那，便能如法“烹煮”（消化）所食之物。

Educational Q&A
Digestion is presented as a regulated process: the digestive fire functions correctly when prāṇa and apāna are balanced and properly situated. The broader ethical suggestion is that harmony of inner forces—order, restraint, and right coordination—sustains life and supports dharmic living.
Bharadvāja explains a yogic-physiological point within Śānti Parva’s instructional discourse: how vital winds (prāṇa and apāna) relate to the digestive fire at the navel region, enabling the proper digestion of consumed food.
