Matsya Purana — Lineage of Yayāti through Yadu and the Deeds of Kārtavīrya Arjuna
जातः करसहस्रेण सप्तद्वीपेश्वरो नृपः वर्षायुतं तपस्तेपे दुश्चरं पृथिवीपतिः //
jātaḥ karasahasreṇa saptadvīpeśvaro nṛpaḥ varṣāyutaṃ tapastepe duścaraṃ pṛthivīpatiḥ //
Born with a thousand hands, that king became the sovereign lord of the seven continents; the ruler of the earth performed severe, difficult austerities for ten thousand years.
This verse does not describe Pralaya directly; it highlights Puranic cosmography (the seven dvīpas) and the extraordinary ascetic power (tapas) by which a king attains universal sovereignty.
It presents the ideal of a ruler who combines worldly authority with disciplined self-restraint—suggesting that legitimate kingship in the Matsya Purana is supported by tapas (ethical and spiritual discipline), not merely conquest.
No explicit Vastu Shastra or temple-ritual rule appears in this verse; its ritual-religious takeaway is the emphasis on long, severe tapas as a means to acquire merit, authority, and divine favor.
