Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
नाधिगच्छाम्यहं नारीं यस्यामेवंविधः सुतः जायेत तस्मादद्याहं भवाम्यथ सहस्रशः //
nādhigacchāmyahaṃ nārīṃ yasyāmevaṃvidhaḥ sutaḥ jāyeta tasmādadyāhaṃ bhavāmyatha sahasraśaḥ //
I find no woman in whom a son of such a kind could be born. Therefore, from this very day, I shall manifest in a thousand forms.
This verse does not directly discuss Pralaya; it focuses instead on a personal resolve about progeny/manifestation, using the motif of becoming “in thousands,” which is a narrative expression of extraordinary agency rather than cosmic dissolution.
In Purāṇic ethical framing, continuity of lineage (putra) is tied to social order and duty; the speaker’s statement reflects anxiety about obtaining a worthy successor and a decisive resolve to act—an echo of the king/householder concern for progeny and stability.
No Vāstu, temple-building, or ritual procedure is specified in this verse; its key idea is narrative transformation/manifestation (sahasraśaḥ), not architectural prescription.
