Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
तयोर्मध्ये तु विज्ञेयो मेरुर्यत्र त्विलावृतम् दक्षिणेन तु नीलस्य निषधस्योत्तरेण तु //
tayormadhye tu vijñeyo meruryatra tvilāvṛtam dakṣiṇena tu nīlasya niṣadhasyottareṇa tu //
Between those two mountain ranges one should understand Mount Meru to be situated—where the region called Ilāvṛta lies—placed to the south of the Nīla mountain and to the north of the Niṣadha mountain.
This verse is not about Pralaya; it gives a cosmographical placement of Mount Meru and Ilāvṛta within the Purāṇic world-map.
Indirectly, it supports dharmic governance by grounding pilgrimage, sacred directionality, and the idea of a divinely ordered world that kings protect and householders honor through rites and tīrtha-travel.
The verse provides cardinal orientation (north/south) and a sacred central axis (Meru), concepts later echoed in Vastu Shastra and temple planning where a central axis and directional alignment are ritually significant.
