Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
हेमपर्वत इत्युक्तः स एव च महीधरः हरितालमयैः शृङ्गैर् द्वीपमावृत्य सर्वशः //
hemaparvata ityuktaḥ sa eva ca mahīdharaḥ haritālamayaiḥ śṛṅgair dvīpamāvṛtya sarvaśaḥ //
That very earth-bearing range is called Hema-parvata; with peaks made of haritāla (yellow orpiment), it encircles the island-continent on every side.
It does not describe pralaya directly; it belongs to cosmographic mapping, portraying how a dvīpa is bounded by a defining mountain range (Hema-parvata) with mineral-like peaks.
Indirectly, it supports the Purāṇic worldview that underlies dharma: kings and householders are taught to see the earth as a sacred, ordered realm with defined regions—useful for pilgrimage ideals, ritual orientation, and righteous governance tied to sacred geography.
Ritually, such cosmographic boundaries inform traditional sacred orientation and the idea of a ‘mandala-like’ ordered world; architecturally, it resonates with Vāstu’s emphasis on enclosing boundaries and directional completeness (surrounding ‘on all sides’), though no direct temple rule is stated in this verse.
