Matsya Purana — Yadu Lineage
*सूत उवाच तेषां दायनिमित्तं ते संग्रामास्तु सुदारुणाः वराहाद्या दश द्वौ च शण्डामर्कान्तरे स्मृताः //
*sūta uvāca teṣāṃ dāyanimittaṃ te saṃgrāmāstu sudāruṇāḥ varāhādyā daśa dvau ca śaṇḍāmarkāntare smṛtāḥ //
Sūta said: Because of disputes over inheritance, those wars became exceedingly dreadful. Twelve wars—beginning with the one called Varāha—are remembered as occurring in the interval associated with Śaṇḍa and Amarka.
This verse does not discuss Pralaya; it focuses on human political history—wars arising from inheritance (dāya) disputes—within a remembered chronological interval.
By tracing “dāya” (inheritance) as the root of brutal wars, the verse implicitly warns rulers and householders that unclear succession and property division can destroy social order; dharmic governance requires orderly inheritance rules and peaceful transfer of authority.
No Vāstu or ritual procedure is stated here; the technical point is historical-chronological: a traditional enumeration of twelve wars (starting with “Varāha”) tied to the Śaṇḍa–Amarka period.
