Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
पूर्वतो निषधस्येदं वेद्यर्धं दक्षिणं स्मृतम् परं त्विलावृतं पश्चाद् वेद्यर्धं तु तदुत्तरम् //
pūrvato niṣadhasyedaṃ vedyardhaṃ dakṣiṇaṃ smṛtam paraṃ tvilāvṛtaṃ paścād vedyardhaṃ tu taduttaram //
To the east of Niṣadha lies the southern half of the Vedi (the sacred enclosure), as tradition states; beyond it is Ilāvṛta. To the west, however, is the northern half of that same Vedi.
This verse is not about Pralaya; it belongs to cosmographic mapping, describing how regions are arranged directionally around Niṣadha and Ilāvṛta using the symbolic model of a Vedi (sacrificial ground).
Indirectly, it supports dharmic life by grounding pilgrimage, territorial understanding, and ritual orientation in a sacred cosmic map—useful for kings (realm conception) and householders (ritual directionality and tirtha-travel).
The key term ‘vedy-ardha’ frames geography through the ritual geometry of the Vedi, echoing how Vastu and yajña layouts rely on precise directional halves (north/south/east/west) for correct placement and meaning.
