Dāyavibhāga (Inheritance Apportionment) and Household Precedence — Dialogue of Yudhiṣṭhira and Bhīṣma
अपत्यजन्म शूद्रायां न प्रशंसन्ति साधव: । शूद्रायां जनयन् वि्र: प्रायश्चित्ती विधीयते
apatyajanma śūdrāyāṁ na praśaṁsanti sādhavaḥ | śūdrāyāṁ janayan vipraḥ prāyaścittī vidhīyate ||
भीष्म ने कहा—शूद्रा के गर्भ से संतान उत्पन्न करना सज्जन नहीं सराहते। जो ब्राह्मण शूद्रा में संतान उत्पन्न करता है, उसके लिए प्रायश्चित्त का विधान है।
भीष्म उवाच
The verse frames a normative rule of conduct: procreation by a brāhmaṇa with a Śūdra woman is treated as blameworthy in the dharma discourse, and therefore requires prāyaścitta (ritual-moral expiation).
In the Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and proper conduct. Here he states a social-ethical injunction concerning varṇa boundaries and the consequent need for expiation when they are transgressed.
