Ācāra-vidhi (Rules of Conduct) — Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Catalogue
भूगुरुवाच वायोग्गतिमहं ब्रह्मन् कथयिष्यामि तेडनघ । प्राणिनामनिलो देहान् यथा चेष्टयते बली
bhṛgur uvāca vāyor gatiṃ ahaṃ brahman kathayiṣyāmi te 'n-agha | prāṇinām anilo dehān yathā ceṣṭayate balī ||
भृगु बोले—“ब्रह्मन्, निष्पाप महर्षे! मैं तुम्हें वायु की गति और कार्य-व्यवस्था बताऊँगा। प्रबल अनिल (प्राणवायु) प्राणियों के शरीरों को जिस प्रकार चेष्टाशील बनाता है, वह मैं वर्णन करता हूँ।”
भरद्वाज उवाच
The verse introduces a teaching on prāṇa/vāyu: the vital air is presented as the powerful principle that animates embodied beings, making bodily functions and movements possible.
Bhṛgu begins an explanatory discourse addressed to a Brahmin sage, announcing that he will describe the ‘movement of Vāyu’ and explain how this force energizes and activates the bodies of living creatures.
