Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
पर्याणप्रत्यभिज्ञानात् सर्वे विस्मयम् आगताः अयं चन्द्रप्रभो नाम वाजी तस्य महात्मनः //
paryāṇapratyabhijñānāt sarve vismayam āgatāḥ ayaṃ candraprabho nāma vājī tasya mahātmanaḥ //
Recognizing it by its saddle-gear, all were struck with wonder: “This is the horse named Candraprabha, belonging to that great-souled man.”
This verse does not discuss pralaya; it is a narrative moment of recognition (via saddle-gear) within a dynastic/courtly episode.
Indirectly, it reflects the royal-world emphasis on proper identification, ownership, and the credibility of tokens/equipment—practical ethics important for governance and social order.
No vastu, temple-architecture, or ritual procedure is taught here; the focus is on narrative identification through the horse’s saddle-gear.
