Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
गन्धमादनपार्श्वे तु पश्चिमे ऽमरगण्डिकः द्वात्रिंशच्च सहस्राणि योजनैः सर्वतः समः //
gandhamādanapārśve tu paścime 'maragaṇḍikaḥ dvātriṃśacca sahasrāṇi yojanaiḥ sarvataḥ samaḥ //
To the west, beside Gandhamādana, lies (the mountain or region called) Amaragaṇḍika; it extends uniformly on all sides for thirty-two thousand yojanas.
This verse is not about Pralaya; it belongs to cosmographic mapping, giving the location and standardized extent of a named region/mountain using yojana measurements.
Indirectly, such geographic catalogues support a king’s ideal of knowing the world’s sacred layout (tīrthas, mountains, realms) for pilgrimage, patronage, and dharmic governance, though no direct duty is stated here.
The technical element is measurement (yojana) and directional placement (west of Gandhamādana), reflecting the Purāṇic habit of precise spatial description—useful as a conceptual backdrop for later Vāstu/mandala thinking, though no temple rule is specified in this verse.
