Shloka 7
Ācāra-vidhi (Rules of Conduct) — Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Catalogue
प्रयत्ने कर्मणि बले य एकस्त्रिषु वर्तते । उदान इति त॑ प्राहुरध्यात्मविदुषो जना:,जिस एक ही वायुकी प्रयत्न, कर्म और बल तीनोंमें प्रवृत्ति होती है, उसे अध्यात्मतत्त्वके जाननेवाले पुरुषोंने उदान कहा है
prayatne karmaṇi bale ya ekas triṣu vartate | udāna iti taṁ prāhur adhyātmaviduṣo janāḥ ||
バラドヴァージャは言った。「努力・行為・力という三つの領域において働く、そのただ一つの生命の風を、自己の真理を知る者たちはウダーナ（Udāna）と呼ぶ。ゆえに、内なる鍛錬と身体の力とは、正しく見分けられるとき、一つの微妙なる生命力の現れとして理解される。」
भरद्वाज उवाच
Educational Q&A
The verse identifies Udāna as the single vital force that manifests as effort, action, and strength—teaching that bodily capacities and disciplined striving are rooted in a subtle inner principle understood by adhyātma-knowers.
In the Śānti Parva’s instructional discourse, Bharadvāja explains a point of adhyātma (inner doctrine) by defining Udāna among the vital winds, describing its functional presence in human exertion and power.
