Matsya Purana — Devayānī–Śarmiṣṭhā Dialogue: Yayāti’s Transgression
शोभनं भीरु सत्यं चेत् कथं स ज्ञायते द्विजः गोत्रनामाभिजनतः श्रोतुमिच्छामि तं द्विजम् //
śobhanaṃ bhīru satyaṃ cet kathaṃ sa jñāyate dvijaḥ gotranāmābhijanataḥ śrotumicchāmi taṃ dvijam //
O gentle one, if truth is indeed the mark of what is noble, then how is a ‘dvija’ (twice-born man) to be recognized? Is it by lineage—by gotra, name, and family descent? I wish to hear of that true dvija.
This verse does not discuss pralaya; it focuses on dharma—how to identify a true dvija and whether truth and conduct outweigh mere lineage.
It frames a governance and social-ethics concern: a king/householder must evaluate people by character (especially truthfulness) rather than relying only on gotra, name, and birth when granting honor, trust, or responsibility.
No Vāstu or temple-architecture rule appears here; the verse is a moral inquiry about social recognition and the standards of dvija identity.
