Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
नारायणात्मकाः सर्वे रामस्तेष्वग्रजो ऽभवत् रावणान्तकरस्तद्वद् रघूणां वंशवर्धनः //
nārāyaṇātmakāḥ sarve rāmasteṣvagrajo 'bhavat rāvaṇāntakarastadvad raghūṇāṃ vaṃśavardhanaḥ //
All of them were of the very essence of Nārāyaṇa; among them, Rāma became the foremost. He was the slayer who brought Rāvaṇa to his end, and likewise the increaser and upholder of the lineage of the Raghu dynasty.
This verse does not address Pralaya; it focuses on avatar-theology and royal genealogy, presenting Rāma as Nārāyaṇa’s essence and as the upholder of the Raghu line.
By praising Rāma as the destroyer of a tyrant (Rāvaṇa) and the “increaser of the dynasty,” the verse aligns kingship with protecting dharma, removing oppressive forces, and sustaining righteous lineage and social order.
No Vāstu, temple-building, or ritual procedure is stated here; the verse is primarily genealogical and theological, emphasizing divine incarnation and dynastic continuity.
