अग्निवंशवर्णनम् (Agni-vaṃśa-varṇana) / The Genealogy and Function of Agni
तपोमूलमिदं सर्व यन्मां विप्रानुपृच्छसि । इन्द्रियाण्येव संयम्य तपो भवति नान्यथा,विप्रवर! आप मुझसे जो कुछ पूछते हैं, उसके उत्तरमें मैं यह बता रहा हूँ कि इस सबका मूल तप है। इन्द्रियोंका संयम करनेसे ही वह तपस्या सम्पन्न होती है, और किसी प्रकारसे नहीं
tapomūlam idaṃ sarvaṃ yan māṃ viprānupṛcchasi | indriyāṇy eva saṃyamya tapo bhavati nānyathā, vipravara |
The hunter said: “O best of brahmins, whatever you are asking me about—its entire foundation is austerity (tapas). That austerity is truly accomplished only by restraining the senses; it is not attained in any other way.”
व्याध उवाच
All higher practice and ethical-spiritual attainment rests on tapas, and tapas is fulfilled specifically through indriya-saṃyama—restraint of the senses. Without self-control, austerity is only a name, not a realized discipline.
In the Vana Parva’s dialogue setting, the hunter (vyādha) responds to a brahmin’s inquiry on dharma by emphasizing that the root of what the brahmin seeks is austerity grounded in sense-restraint, offering practical ethical instruction rather than mere ritual theory.
