Baka Dālbhya at Avakīrṇa-tīrtha: Rāṣṭra-kṣaya and Release through Prasāda (Śalya-parva, Adhyāya 40)
तपसा तु तथा युक्त विश्वामित्रं पितामह:
tapasā tu tathā yuktaṃ viśvāmitraṃ pitāmahaḥ
అప్పుడు పితామహుడు తపస్సుతో యుక్తుడైన విశ్వామిత్రుని చూచి, అతని తపోబలాన్ని అంగీకరించాడు।
वैशग्पायन उवाच
Austerity (tapas) and disciplined self-effort can confer real potency and recognition; ethical strength is not only inherited or granted, but also cultivated through sustained practice.
The narrator indicates that the Grandsire observes or acknowledges Viśvāmitra as being 'endowed with tapas,' setting up or reinforcing Viśvāmitra’s stature and the effectiveness of his ascetic power within the episode.
