Ādi Parva, Adhyāya 181 — Svayaṃvara Aftermath: Arjuna–Karna Exchange and Bhīma–Śalya Contest
वसिष्ठश्न महाभाग: सर्वमेतदवैक्षत । ज्ञानयोगेन महता तपसा च परंतप,शत्रुसूदन अर्जुन! महाभाग वसिष्ठजी अपनी बड़ी भारी तपस्या तथा ज्ञानयोगके प्रभावसे ये सब बातें जानते थे
Vasiṣṭhaḥ sa mahābhāgaḥ sarvam etad avaikṣata | jñānayogena mahatā tapasā ca parantapa ||
The illustrious sage Vasiṣṭha perceived and understood all these matters—through the great power of disciplined knowledge (jñāna-yoga) and through austerity. The verse underscores that true insight is earned by inner discipline and spiritual practice, not by mere hearsay or worldly status.
गन्धर्व उवाच
Authentic knowledge and moral authority arise from jñāna-yoga (disciplined insight) and tapas (austerity/self-control); a sage perceives truth through inner cultivation rather than external power.
The Gandharva states that the great sage Vasiṣṭha had already discerned all the relevant facts, because his spiritual disciplines—knowledge-yoga and austerity—gave him penetrating understanding.
