कुत्र चास्य निवासः स्याद् भोजनं वा किमात्मकम् विधास्यतीह भगवान् वीर्यतुल्यं महौजसः //
kutra cāsya nivāsaḥ syād bhojanaṃ vā kimātmakam vidhāsyatīha bhagavān vīryatulyaṃ mahaujasaḥ //
“And where is his dwelling to be, and what kind of food is he to have? How will the Blessed Lord—mighty, of great splendor, and matching him in power—make these arrangements here?”
It reflects the practical, survival-focused concerns that arise in the Pralaya narrative—questions of shelter and sustenance—framing dissolution not only as cosmic but also as a lived event requiring divine instruction and provisioning.
Manu’s questioning models responsible leadership: anticipating necessities (residence and food) for those under protection. In Purāṇic ethics, foresight, planning, and seeking dharmic counsel are key royal/householder duties in times of crisis.
While not a direct Vāstu rule, the verse foregrounds the Vāstu-adjacent theme of ‘nivāsa’ (proper dwelling) and orderly provisioning—principles that later Vāstu/ritual sections formalize as correct siting, habitation planning, and regulated supplies for sacred or communal life.
