Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
सार्धमर्केण सो ऽपश्यन् नीयमानामथाम्बरे केशिना दानवेन्द्रेण चित्रलेखामथोर्वशीम् //
sārdhamarkeṇa so 'paśyan nīyamānāmathāmbare keśinā dānavendreṇa citralekhāmathorvaśīm //
Then he, together with Arka (the Sun), saw Citralekhā and Urvaśī being carried away through the sky by Keśin, the lord of the Dānavas.
This verse does not discuss pralaya; it depicts a mythic event where a Daitya king (Keśin) abducts Urvaśī and Citralekhā through the sky.
Indirectly, it frames adharma as forcible abduction and violence by a powerful ruler; the broader Purāṇic ethic contrasts such acts with a king’s duty to protect and uphold dharma.
No explicit Vāstu, temple-architecture, or ritual procedure is stated in this verse; it is primarily narrative, involving celestial movement and abduction.
