Matsya Purana — Prologue to the Matsya Purana and the Manu–Pralaya Rescue Narrative
नौर् इयं सर्वदेवानां निकायेन विनिर्मिता महाजीवनिकायस्य रक्षणार्थं महीपते //
naur iyaṃ sarvadevānāṃ nikāyena vinirmitā mahājīvanikāyasya rakṣaṇārthaṃ mahīpate //
O king, this boat has been fashioned by the assembled host of all the gods for the protection of the great multitude of living beings.
It frames pralaya as a cosmic crisis in which divine forces proactively arrange preservation—here, the gods collectively provide a boat to safeguard life through the deluge.
By addressing Manu as “mahīpati,” it implies that righteous leadership includes protecting and sustaining the community of beings, especially in times of calamity, aligning kingship with guardianship (rakṣaṇa).
While not a Vastu rule, the verse highlights a ritual-cosmic principle: divinely sanctioned construction (a life-preserving vessel) made for a specific dharmic purpose—protection and continuity of beings.
