Matsya Purana — Division of Bhārata-varṣa
यस्त्वयं मानवो द्वीपस् तिर्यग्यामः प्रकीर्तितः य एनं जयते कृत्स्नं स सम्राडिति कीर्तितः //
yastvayaṃ mānavo dvīpas tiryagyāmaḥ prakīrtitaḥ ya enaṃ jayate kṛtsnaṃ sa samrāḍiti kīrtitaḥ //
This very ‘Mānava’ continent, famed for its breadth (east–west), is thus proclaimed; whoever conquers it in its entirety is celebrated as a ‘Samrāṭ’ (universal sovereign).
It does not discuss Pralaya directly; it belongs to the Purana’s cosmographic mapping of the world and defines political sovereignty (Samrāṭ) in relation to conquering a named dvīpa.
It frames an ideal of kingship: a ruler who unifies and subdues the entire Mānava-dvīpa earns the title Samrāṭ—implying political integration, protection, and effective governance as hallmarks of legitimate imperial rule.
No Vāstu or ritual procedure is stated; the verse is primarily political-geographic, using the dvīpa framework to define the scope of ‘universal’ rule.
