Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
विष्कम्भपर्वतास्तद्वन् मन्दरो गन्धमादनः विपुलश्च सुपार्श्वश्च सर्वरत्नविभूषिताः //
viṣkambhaparvatāstadvan mandaro gandhamādanaḥ vipulaśca supārśvaśca sarvaratnavibhūṣitāḥ //
Likewise there are the supporting, buttress-like mountains: Mandara, Gandhamādana, Vipula, and Supārśva—each adorned with every kind of precious gem.
This verse is not describing Pralaya directly; it presents a stable cosmic geography in which the world is upheld by “supporting mountains,” emphasizing order and structure in creation.
Indirectly, it models the ideal of “support” and stability: just as the world is sustained by supporting mountains, kings and householders are expected to uphold social order through protection, generosity, and maintenance of dharma.
The imagery of ‘supporting’ structures and gem-adornment parallels Vastu and temple ideals—firm foundations and auspicious embellishment—though this particular verse is primarily cosmographic rather than a direct building rule.
