Matsya Purana — Kailasa
तस्य पादे महद्दिव्यं लोहितं सुमहत्सरः तस्मात्प्रभवते पुण्यो लौहित्यश्च नदो महान् //
tasya pāde mahaddivyaṃ lohitaṃ sumahatsaraḥ tasmātprabhavate puṇyo lauhityaśca nado mahān //
At his foot there is a vast, divine lake called Lohita. From that lake arises the holy and mighty river known as Lauhitya.
This verse is not about Pralaya; it belongs to sacred geography, explaining the divine source of a holy river arising from a lake at a revered being’s foot.
Indirectly, it supports dharmic life by identifying a sacred river and tirtha: kings and householders gain merit through honoring such holy waters, supporting pilgrimages, and maintaining ritual purity.
Ritually, the key point is the sanctity of Lauhitya’s waters—appropriate for snāna (sacred bathing), offerings to ancestors, and tirtha-related rites; no specific Vastu or temple-construction rule is stated in this verse.
