Matsya Purana — Description of Pralaya: Drying
न द्रष्टा नैव गमिता न ज्ञाता नैव पार्श्वगः तस्य न ज्ञायते किंचित् तमृते देवसत्तमम् //
na draṣṭā naiva gamitā na jñātā naiva pārśvagaḥ tasya na jñāyate kiṃcit tamṛte devasattamam //
He has no (separate) seer, no one who can reach Him, no knower, nor any attendant standing beside Him. Nothing whatsoever is truly known of Him—except that He is the most excellent among the gods.
Indirectly, it frames the Supreme as beyond all ordinary knowing or reaching—implying that even cosmic events like pralaya are ultimately governed by a reality that transcends description and human categories.
It encourages humility and dharmic conduct: since the Supreme cannot be fully grasped by intellect or proximity, a king or householder should rely on dharma, devotion, and righteous governance rather than pride in knowledge or power.
No direct Vastu or ritual rule is stated; the takeaway for ritual practice is theological—worship is directed to a transcendent Supreme who is not an object fully captured by senses or concepts, so rites should be performed with reverence and humility.
