Matsya Purana — The Greatness and Procedure of the Sarva-Phala-Tyaga Vrata
विप्राय दत्त्वा भुञ्जीत वाग्यतस्तैलवर्जितम् अन्यान्यपि यथाशक्त्या भोजयेच्छक्तितो द्विजान् //
viprāya dattvā bhuñjīta vāgyatastailavarjitam anyānyapi yathāśaktyā bhojayecchaktito dvijān //
After first offering food to a brāhmaṇa, one should then eat in silence and without oil; and, according to one’s ability, one should also feed other twice-born (dvija) persons as far as one’s means allow.
This verse does not discuss pralaya; it focuses on dharma—proper conduct around eating, charity, and honoring brāhmaṇas.
It prescribes a householder/kingly ethic of dana and hospitality: offer food first to a brāhmaṇa, practice self-restraint (silence), and support other dvijas according to one’s resources—an ideal of disciplined consumption and social-religious responsibility.
The ritual significance is the bhojana-vidhi: prioritizing feeding brāhmaṇas and observing restraint (vāgyata) and simplicity (taila-varjita) as part of vrata-like purity and disciplined living.
