Matsya Purana — Tripura’s Prosperity
सकलत्राः सपुत्राश्च शस्त्रवन्तो ऽन्तकोपमाः मयादिष्टानि विविशुर् गृहाणि हृषिताश्च ते //
sakalatrāḥ saputrāśca śastravanto 'ntakopamāḥ mayādiṣṭāni viviśur gṛhāṇi hṛṣitāśca te //
Together with their wives and sons, armed and, in their fierce resolve, resembling Death itself, they entered the houses I had assigned—glad at heart.
This verse does not directly discuss pralaya; it emphasizes organized action and protective readiness—people entering assigned dwellings under command—within a narrative setting.
It reflects disciplined social order: families (with wives and sons) obey instructions, take up protective readiness, and occupy designated homes—echoing the kingly duty of orderly settlement and the householder’s duty of safeguarding the household.
Architecturally, the verse implies allocation/assignment of dwellings (gṛhāṇi) and orderly occupation; it does not state specific Vastu rules, but it supports the broader Vastu/settlement idea of designated residences and regulated entry.
