Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
सत्यभामा वरा स्त्रीणां व्रतिनी च दृढव्रता तथा पद्मावती चैव ताश्च कृष्णाय सो ऽददात् //
satyabhāmā varā strīṇāṃ vratinī ca dṛḍhavratā tathā padmāvatī caiva tāśca kṛṣṇāya so 'dadāt //
Satyabhāmā—foremost among women—together with Vratinī of steadfast vows, and likewise Padmāvatī: all of them he gave in marriage to Kṛṣṇa.
This verse does not discuss Pralaya; it belongs to a dynastic narrative describing marital bestowal and lineage-related alliances.
It reflects the dharmic institution of marriage as a sanctioned social bond; in royal contexts, such unions also function as alliances that stabilize lineage and polity.
No Vastu, temple-building, or ritual procedure is stated here; the verse is focused on persons and marriage bestowal rather than architecture or iconography.
