Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
*सूत उवाच एतदेव पुरा पृष्टः शतानीकेन शौनकः पुण्यं पवित्रमायुष्यं ययातिचरितं महत् //
*sūta uvāca etadeva purā pṛṣṭaḥ śatānīkena śaunakaḥ puṇyaṃ pavitramāyuṣyaṃ yayāticaritaṃ mahat //
Sūta said: Long ago, Śatānīka asked Śaunaka this very matter—namely, the great narrative of King Yayāti, which is meritorious, purifying, and life-enhancing.
This verse does not discuss Pralaya; it introduces the Yayāti narrative and emphasizes its purifying, merit-giving, and longevity-bestowing value.
By foregrounding a royal biography (Yayāti-carita), the verse frames kingship narratives as ethical instruction—implying that rulers and householders gain merit and guidance by hearing exemplary (and cautionary) accounts of royal conduct.
No Vāstu/temple-building rule is stated here; the ritual significance is the śravaṇa-phala idea—hearing sacred history is described as puṇya (merit), pavitra (purifying), and āyuṣya (promoting longevity).
