Matsya Purana — Yadu Lineage
चतस्रो जज्ञिरे तेषां स्वसारस्तु यवीयसीः जाम्बवत्याः सुतो जज्ञे साम्बः समितिशोभनः //
catasro jajñire teṣāṃ svasārastu yavīyasīḥ jāmbavatyāḥ suto jajñe sāmbaḥ samitiśobhanaḥ //
Among them, four sisters were born, and the youngest of those sisters was also born. From Jāmbavatī was born a son—Sāmba—who was splendid in the assembly of warriors (and in battle).
This verse does not discuss Pralaya; it is part of a dynastic genealogy describing births within a royal/divine family line.
Indirectly, it supports the Purana’s emphasis on lineage, progeny, and rightful succession—key concerns for householders and kings in maintaining dharma through family continuity.
No Vastu, temple, or ritual procedure is stated here; the focus is purely genealogical, highlighting notable offspring and family relations.
