Matsya Purana — Kailasa
तीरे वंशौकसारायाः सुरभिर्नाम तद्वनम् हिरण्यशृङ्गो वसति विद्वान्कौबेरको वशी //
tīre vaṃśaukasārāyāḥ surabhirnāma tadvanam hiraṇyaśṛṅgo vasati vidvānkauberako vaśī //
On the bank of the Vaṃśaukasārā River lies a forest named Surabhi. There dwells Hiraṇyaśṛṅga—wise, self-controlled, and a Kauberaka (a Yakṣa of Kubera’s retinue).
This verse does not discuss Pralaya; it situates a specific sacred landscape—naming a riverbank forest and its guardian-like resident associated with Kubera.
Indirectly, it supports the Purāṇic ideal of honoring tīrthas and protected sacred spaces; a king/householder gains merit by respecting such sites and the disciplined, wise beings (like a vaśī) who dwell there.
No explicit Vāstu rule is stated, but the verse functions as a tīrtha-marker: such named forests on riverbanks are typical ritual geographies for pilgrimage, bathing, offerings, and establishing hermitages/holy precincts.
