Prāyaścitta-vidhāna: Tapas, Dāna, Vrata, and Proportional Expiation (प्रायश्चित्तविधानम्)
सुरानुगतमुच्छिष्टमभोज्यं शेषितं च यत् । “बायें हाथसे लाया अथवा परोसा गया अन्न, बासी भात, शराब मिला हुआ, जूठा और घरवालोंको न देकर अपने लिये बचाया हुआ अन्न भी अखाद्य ही है
surānugatam ucchiṣṭam abhojyaṁ śeṣitaṁ ca yat |
Vyāsa said: Food tainted by intoxicants, food that is leftover or defiled (ucchiṣṭa), and any food kept back for oneself after others have been served—such food is to be regarded as unfit to eat. The teaching upholds purity, self-restraint, and the ethic of not placing one’s own consumption above one’s household or dependents.
व्यास उवाच
One should avoid food that is ritually/ethically impure—especially food tainted by intoxicants, leftovers/defiled remnants, and food selfishly reserved for oneself before serving others—because right conduct (dharma) includes purity, restraint, and consideration for dependents.
In Śānti Parva’s instruction on dharma and proper conduct, Vyāsa enumerates categories of food deemed unfit to eat, using dietary discipline as a practical expression of ethical living.
