Matsya Purana — The Greatness of the Vibhūti-Dvādaśī Vow: Pushkara
भोजनं च सुहृन्मित्रदीनान्धकृपणैः समम् तच्च लुब्धकदाम्पत्यं पूजयित्वा विसर्जितम् //
bhojanaṃ ca suhṛnmitradīnāndhakṛpaṇaiḥ samam tacca lubdhakadāmpatyaṃ pūjayitvā visarjitam //
He should share his meal equally with well-wishers and friends, and also with the poor, the blind, and the destitute; and having duly honoured even the greedy hunter-couple, he should then respectfully send them on their way.
Nothing directly—this shloka is ethical instruction (gṛhastha-dharma), emphasizing compassion and impartial sharing of food rather than cosmology or Pralaya.
It teaches the householder (and by extension a righteous ruler) to practice non-discriminatory hospitality—feeding friends and the vulnerable (poor, blind, destitute) and honoring even socially marginal guests, reflecting dharma as social welfare and self-restraint.
Ritually, it supports atithi-satkāra (guest-honoring) and charitable feeding as a dharmic act; it does not give Vastu/temple-building rules in this verse.
