श्रूयते यच्च वै श्राव्यं यच्चान्यत्परिजल्प्यते याः कथाश्चैव वर्तन्ते श्रुतयो वाथ तत्पराः विश्वं विश्वपतिर्यश्च स तु नारायणः स्मृतः //
śrūyate yacca vai śrāvyaṃ yaccānyatparijalpyate yāḥ kathāścaiva vartante śrutayo vātha tatparāḥ viśvaṃ viśvapatiryaśca sa tu nārāyaṇaḥ smṛtaḥ //
Whatever is heard, whatever is fit to be heard, and whatever else is spoken of; whatever narratives circulate, and even the Vedic revelations that are devoted to that truth—all of this is the universe, and He who is the Lord of the universe is remembered as Nārāyaṇa.
While not describing Pralaya directly, it frames a key Purāṇic principle: all phenomena and all authoritative sacred testimony ultimately point to Nārāyaṇa as the cosmic totality (viśva) and its sovereign (viśvapati), implying He remains the ultimate ground through creation, preservation, and dissolution.
It redirects dharma toward right listening (śrāvya) and right discourse: a king or householder should prioritize hearing and speaking what aligns with Śruti-centered truth—i.e., teachings that cultivate devotion, ethical conduct, and God-centered governance rather than idle or harmful talk.
No explicit Vāstu or temple-rule is stated; the ritual takeaway is interpretive: all recitation, hearing, and sacred storytelling (kathā, śruti) are validated when oriented toward Nārāyaṇa—supporting practices like Purāṇa-śravaṇa (listening to Purāṇas) and Viṣṇu-centered liturgy.
