Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
नाम्ना सर्वसुखो नाम दिव्यौषधिसमन्वितः तृतीयश्चैव सौवर्णो भृङ्गपत्त्रनिभो गिरिः //
nāmnā sarvasukho nāma divyauṣadhisamanvitaḥ tṛtīyaścaiva sauvarṇo bhṛṅgapattranibho giriḥ //
The mountain known as Sarvasukha is endowed with divine medicinal herbs; and the third is Sauvarṇa, a mountain whose appearance is like the leaf of the bhṛṅga plant.
This verse is not a Pralaya passage; it belongs to cosmographic description, highlighting sacred mountains and the presence of divine medicinal herbs as features of the ordered world.
Indirectly, it supports the Purana’s worldview where kings and householders uphold dharma by protecting sacred landscapes and resources (like medicinal herbs) that sustain health and ritual life.
No direct Vastu rule appears here; the ritual takeaway is the sacrality of geography—mountains rich in divyauṣadhi are treated as auspicious zones, often linked (in broader Puranic practice) to pilgrimage and sanctified collection of herbs for rites.
