Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
रजिपुत्रैस्तदाच्छिन्नं बलादिन्द्रस्य वैभवम् यज्ञभागं च राज्यं च तपोबलगुणान्वितैः //
rajiputraistadācchinnaṃ balādindrasya vaibhavam yajñabhāgaṃ ca rājyaṃ ca tapobalaguṇānvitaiḥ //
Then the sons of Raji—endowed with the power born of austerity and virtue—by force seized Indra’s splendour, together with his share in the sacrifices and his sovereignty.
This verse does not describe Pralaya; it focuses on a Manvantara-era power shift where Raji’s sons seize Indra’s glory and sacrificial entitlement.
It implies that sovereignty is tied to dharmic merit—especially tapas and virtues—and that control over yajña (public ritual order) is a core marker of legitimate rulership.
The ritual significance is the mention of yajñabhāga—the formal ‘share’ in sacrifices—indicating that ritual entitlement and cosmic governance are institutionally linked in Purāṇic thought.
