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 ||
その二人が聡明にしてヴェーダに堅く通暁しているのを見て、力ある師はヴェーダの意義をいよいよ増し支えるために、この叙事詩を彼らに授けた。
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.
