Ācāra-vidhi (Rules of Conduct) — Yudhiṣṭhira’s Inquiry and Bhīṣma’s Normative Catalogue
अग्निवेगवह:ः प्राणो गुदान्ते प्रतिहन्यते । स ऊर्ध्वमागम्य पुन: समुत्क्षिपति पावकम्,अग्निके वेगसे बहता हुआ प्राण गुदाके निकट जाकर प्रतिहत हो जाता है; फिर ऊपरकी ओर लौटकर समीपवर्ती अग्निको भी ऊपर उठा देता है
agnivegavahaḥ prāṇo gudānte pratihanyate | sa ūrdhvam āgamya punaḥ samutkṣipati pāvakam |
ويشرح بهاردفاجا: إن الپرَانا، الجاري بدفعٍ كدفع النار، يصطدم بعائق قرب نهاية المستقيم. ثم يرتد صاعدًا، فيرفع النار الباطنة القريبة ويُذكيها.
भरद्वाज उवाच
The verse teaches that bodily life is governed by regulated movements of prāṇa and agni; understanding these inner dynamics supports restraint, balance, and disciplined conduct rather than impulsive living.
Bharadvāja describes prāṇa moving with fiery force, being checked near the anal region, then rebounding upward and thereby raising/activating the nearby inner fire (pāvaka), as part of an explanation of internal bodily processes.
