Abhaya-Itihāsa: Karma, Indriyas, and the Non-sensory Brahman
Brāhmaṇī–Brāhmaṇa Saṃvāda
प्राणानामायतत्वेन तमुदान प्रचक्षते । तस्मात् तपो व्यवस्यन्ति मद्गतं ब्रह्म॒वादिन:
prāṇānām āyatatvena tam udāna pracakṣate | tasmāt tapo vyavasyanti madgataṁ brahmavādinaḥ ||
பிராணங்களின் ஆதாரமாக இருப்பதால் ஞானிகள் அதனை ‘உதானன்’ என்று கூறுகின்றனர். ஆகவே வேதவாதிகள் தவத்தை என்னிடமே நிலைநிறுத்தி, என்னிடமே உறுதி செய்கின்றனர்.

Educational Q&A
Udāna is identified as the sustaining basis connected with the vital breaths, and true austerity (tapas) is presented as a disciplined resolve grounded in Vāyu’s principle—linking spiritual practice with mastery and understanding of prāṇa.
Vāyudeva is speaking doctrinally, explaining a subtle physiological-spiritual concept: why the wise name a particular vital function ‘Udāna’ and how Veda-knowers, on that basis, commit themselves to tapas as a practice established in Vāyu.
