Matsya Purana — Yayāti’s Forest-Renunciation
अतिथीन् पूजयन्नित्यं वन्येन हविषा विभुः शिलोञ्छवृत्तिमास्थाय शेषान्नकृतभोजनः //
atithīn pūjayannityaṃ vanyena haviṣā vibhuḥ śiloñchavṛttimāsthāya śeṣānnakṛtabhojanaḥ //
Ever honouring guests with forest-offerings—simple produce of the wild—that noble man should adopt the ‘śiloñcha’ mode of livelihood, and eat only after the guests, taking food solely from what remains.
This verse does not discuss pralaya directly; it teaches dharma—daily hospitality and restraint—presenting ethical order (dharma) as the stabilizing principle of life rather than a cosmological event.
It sets a high standard for the gṛhastha (and by extension a righteous king): honour guests every day, offer them the best available simple food, live by modest means (śiloñcha), and eat only after others are served—an ethic of self-restraint and public-minded generosity.
Ritually, it emphasizes ‘havis’—food fit to be offered—here sourced as vanya (forest produce), highlighting purity and simplicity in offerings; it contains no direct Vāstu/temple-architecture rule but reflects the broader ritual economy that supports yajña and guest-reception.
