Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
यक्षराक्षसगन्धर्वैर् नित्यं सेवितकंदरः हेमगर्भो महाशैलस् तथा हेमसखो गिरिः //
yakṣarākṣasagandharvair nityaṃ sevitakaṃdaraḥ hemagarbho mahāśailas tathā hemasakho giriḥ //
Its caves are constantly frequented by Yakṣas, Rākṣasas, and Gandharvas. There is also the great mountain called Hemagarbha (“Golden-womb”), and likewise the peak named Hemasakha (“Companion of Gold”).
This verse does not describe Pralaya; it belongs to a geographic catalogue, emphasizing how certain mountains and their caves are portrayed as perpetually inhabited by semi-divine and supernatural beings.
Indirectly, such passages frame the sacred landscape a king may protect and a householder may honor through pilgrimage and reverence—acknowledging that remote mountains are imagined as domains of powerful beings and thus approached with restraint and ritual respect.
No direct Vastu or temple-building rule is stated; the ritual takeaway is that caves and mountains are treated as charged sacred spaces (abodes of Yakshas/Gandharvas), supporting pilgrimage culture and the sanctification of natural sites in Puranic practice.
