จากเขานั้นได้บังเกิดอุทานะ; บุตรของอุทานะคือวยานะ. ถัดไปพึงรู้ว่าอปานะเป็นผู้สืบสายของเขา; และจากอปานะนั้น ต่อมาได้อุบัติปราณะ.

Educational Q&A
The verse teaches an ordered understanding of the vital airs (prāṇas) by presenting them in a generative sequence. The ethical implication is that embodied life is governed by intelligible, interlinked functions; knowing this order supports self-control and contemplative insight rather than living impulsively.
In the Śānti Parva’s instruction section, Bhīṣma continues his didactic exposition to Yudhiṣṭhira. Here he enumerates the vital airs—Udāna, Vyāna, Apāna, and Prāṇa—using kinship language (“son/offspring”) to indicate derivation and systematic relation among physiological principles.
