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.
