Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
कैलासशिखराकारं यत्कृतं विश्वकर्मणा रक्ततोयो महाभीमो लौहित्यो नाम सागरः //
kailāsaśikharākāraṃ yatkṛtaṃ viśvakarmaṇā raktatoyo mahābhīmo lauhityo nāma sāgaraḥ //
There is a sea named Lauhitya—terrifying and vast—whose waters are red; it is said to have been fashioned by Viśvakarman, shaped like the peak of Mount Kailāsa.
It does not describe Pralaya directly; it presents a cosmographic origin-story in which a specific sea (Lauhitya) is ‘made’ by Viśvakarman, emphasizing purposeful divine ordering of the world’s geography.
Indirectly, it supports the Purāṇic ideal that rulers and householders should honor sacred geography—protecting tīrthas and waters, and undertaking pilgrimages or donations connected to such places as part of dharma.
By naming Viśvakarman and comparing the form to Kailāsa’s peak, the verse uses an architectural analogy—divine craftsmanship and ideal form—often echoed in Matsya Purana themes about sacred design, proportion, and auspicious natural/constructed shapes.
