भरद्वाज उवाच
The verse teaches an ordered understanding of the body: digestive organs have specific locations relative to the navel, and the navel-region is presented as a central seat of the vital airs (prāṇas). Such knowledge supports disciplined conduct and yogic/ethical self-regulation.
In Śānti Parva’s instructional setting, Bharadvāja is explaining bodily structure and the placement of vital functions, as part of a broader discourse on inner discipline and the foundations for right living.
