तृतीयः सर्गः (Bālakāṇḍa 3): Vālmīki’s Yogic Verification and the Epic Synopsis
स तु मेधाविनौ दृष्ट्वा वेदेषु परिनिष्ठितौ |
वेदोपबृंहणार्थाय तावग्राहयत प्रभुः ||
sa tu medhāvinau dṛṣṭvā vedeṣu pariniṣṭhitau |
vedopabṛṃhaṇārthāya tāvagrāhayata prabhuḥ ||
वे समर्थ प्रभु (वाल्मीकि) उन दोनों मेधावी (लव-कुश) को वेदों में निष्ठावान देखकर, वेदार्थ की पुष्टि के लिए उन्हें यह महाकाव्य पढ़ाते हैं।
Valmiki chose them because he observed they were 'medhāvinau' (highly intelligent) and 'vedeṣu pariniṣṭhitau' (expertly grounded in the Vedas), ensuring they had the intellectual and spiritual foundation to hold the epic.
The verse explicitly states 'vedopabṛṃhaṇārthāya', meaning the Ramayana was taught to expand upon, reinforce, and illustrate the abstract truths of the Vedas through narrative.
