Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
ततस्ते ददृशुः सर्वे वडबाम् अग्रतः स्थिताम् रत्नपर्याणकिरणदीप्तकायाम् अनुत्तमाम् //
tataste dadṛśuḥ sarve vaḍabām agrataḥ sthitām ratnaparyāṇakiraṇadīptakāyām anuttamām //
Then they all beheld, standing before them, a wondrous mare (Vaḍabā), unsurpassed, her body blazing with the radiance of rays reflected from jeweled ornaments.
It presents a striking, luminous apparition (the jeweled, radiant mare) as an omen-like manifestation within the lead-up to the pralaya sequence, emphasizing the extraordinary signs that precede cosmic upheaval.
By portraying an unmistakable marvel appearing directly before witnesses, the verse supports a Purāṇic ethic: rulers and householders should be attentive to dharmic signs and instructions that arise in times of crisis, responding with discipline and preparedness rather than denial.
No explicit Vāstu or temple rule is stated; however, the focus on auspicious brilliance (ratna-kiraṇa-dīpti) aligns with ritual aesthetics where radiance, purity, and ornamentation signify divinity and auspicious presence.
