भविष्यति च तत्रैव पञ्चविंशतिमं यदा कृतं नाम युगं तत्र हैहयान्वयवर्धनः भविता नृपतिर्वीरः कृतवीर्यः प्रतापवान् //
bhaviṣyati ca tatraiva pañcaviṃśatimaṃ yadā kṛtaṃ nāma yugaṃ tatra haihayānvayavardhanaḥ bhavitā nṛpatirvīraḥ kṛtavīryaḥ pratāpavān //
And there itself, when the twenty-fifth age called the Kṛta Yuga arrives, there will be born a heroic king—Kṛtavīrya, mighty in splendour—who will expand the lineage of the Haihayas.
This verse does not describe Pralaya; it is a prophetic-chronological note about the appearance of King Kṛtavīrya in a specified Kṛta Yuga cycle and the expansion of the Haihaya line.
Indirectly, it frames kingship as a dharmic institution across Yugas: a ‘vīra’ and ‘pratāpavān’ ruler is presented as one who strengthens and stabilizes a lineage—an ideal connected to rajadharma (protecting order and continuity).
No Vāstu, temple-building, or ritual procedure is mentioned in this verse; its focus is dynastic prophecy and Yuga-based chronology.
