Matsya Purana — Duties of the Four Āśramas and the Power of Mauna
अनग्निरनिकेतश् चाप्य् अगोत्रचरणो मुनिः कौपीनाच्छादनं यावत् तावदिच्छेच्च चीवरम् //
anagniraniketaś cāpy agotracaraṇo muniḥ kaupīnācchādanaṃ yāvat tāvadicchecca cīvaram //
A sage should live without maintaining a sacrificial fire and without a fixed home; moving about without attachment to lineage or clan, he should desire only so much clothing as is needed for a loincloth (kaupīna) and mere covering—no more.
This verse does not describe pralaya directly; it teaches inner preparedness for impermanence—living without fixed supports (home, possessions), which aligns with a worldview where all conditioned things can pass away.
It contrasts royal/householder responsibilities with the renunciant ideal: kings and householders sustain fire rites and homes, while the muni models restraint and non-attachment—an ethical standard that rulers are urged to honor and protect.
Ritually, it implies the muni does not maintain the domestic/sacrificial fire and does not establish a permanent residence—so temple/house construction and household ritual infrastructure are intentionally renounced in favor of wandering simplicity.
