Rishi: Vasiṣṭha (traditional attribution for RV 3.8 in the Vasiṣṭha family book)
Devata: Vanaspati / sacrificial post and the deities supporting the yajña (contextual); inner sense: the divine formative power that establishes the rite and uplifts consciousness
Chandas: Triṣṭubh (probable for this section; requires full hymn metrical verification)
yuvā́ su-vāsā́ḥ párivīta ā́gāt sá u śréyān bhavati jā́yamānaḥ | táṃ dhīrā́saḥ kaváya ún nayanti svādhyò manasā devayántaḥ ||
Translation
Yeh naujawan hai, ache kapde pehne, apni chamak se dhaka hua. Paidalte hi woh sabse bada ban jata hai. Rishi log use uthaate hain, jo apne mann ko sambhal ke bhagwan ki taraf le jaate hain.
