Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
स्फीतक्रोडावलम्बेन शीतांशुसमतेजसा भोगिभोगावसक्तेन मणिरत्नेन भास्वता //
sphītakroḍāvalambena śītāṃśusamatejasā bhogibhogāvasaktena maṇiratnena bhāsvatā //
It shines with a radiant jewel—hanging from a broad, prominent chest—whose brilliance is like the cool-rayed moon, set upon the coils of a serpent and gleaming with gem-like splendor.
This verse is not about Pralaya; it is a descriptive iconographic/ornamental detail emphasizing auspicious radiance (moon-like brilliance) and nāga/serpent-associated adornment.
Indirectly, it supports the dharmic duty of patrons (kings/householders) to commission properly described sacred images and temple ornaments, ensuring auspiciousness, beauty, and scriptural conformity in worship spaces.
It highlights prescribed visual qualities for sacred ornamentation—placement (hanging on the chest), material (precious jewel), and auspicious symbolism (moon-like cool brilliance; serpent-coil setting)—useful for pratima-lakshana and temple decorative standards.
