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 ||
婆罗陀婆阇说道：“那同一股生命之风，在三处领域中运作——精进、行为与力量——知自性真实者称之为‘优陀那’（Udāna）。因此，内在的修持与身体的劲力，若能如实辨知，皆是一种微妙生命力的显现。”

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.
