बलीन्द्रसंवादः — Kāla, Anityatā, and the Limits of Agency
Mahābhārata 12.217
प्रकाशस्तपसो ज्ञानं लोके संशब्दितं तप: । रजस्तमोघ्नं यत् कर्म तपसस्तत् स्वलक्षणम्
bhīṣma uvāca | prakāśas tapaso jñānaṃ loke saṃśabditaṃ tapaḥ | rajas-tamo-ghnaṃ yat karma tapasas tat svalakṣaṇam |
Bhishma dit : Dans le monde, on parle du tapas comme de ce dont le fruit est la lumière — à savoir la connaissance. L’acte qui détruit le rajas et le tamas, accompli sans mobile égoïste, est la marque qui fait reconnaître la véritable austérité.
भीष्म उवाच
True tapas is not mere physical hardship; it is disciplined, motive-free action that reduces rajas (agitation/desire) and tamas (inertia/delusion), culminating in prakāśa—illumination in the form of jñāna (knowledge).
In the Shanti Parva’s instruction on dharma and right conduct, Bhishma teaches Yudhishthira by defining the hallmark of genuine austerity: ethical, selfless action that purifies the mind and yields clarity and knowledge.
