Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
रत्ना कन्या च शैब्यस्य अक्रूरस्तामवाप्तवान् पुत्रानुत्पादयामास एकादश महाबलान् //
ratnā kanyā ca śaibyasya akrūrastāmavāptavān putrānutpādayāmāsa ekādaśa mahābalān //
Ratnā, the daughter of Śaibya—Akrūra took her as his wife, and he begot eleven sons of great strength.
This verse does not address Pralaya; it functions as a genealogical record, noting marriage and progeny to preserve dynastic continuity.
Indirectly, it reflects the householder ideal of marriage and lawful progeny, a key theme in Purāṇic social order and lineage preservation.
No Vāstu, temple-building, or ritual procedure is mentioned; the verse is purely genealogical (names, marriage, and offspring).
