प्रतिग्रहभेदः — The Distinction between Giving and Accepting
Vṛṣādarbhī–Saptarṣi Dialogue
चाण्डालश्वपचौ वर्ज्यौ निवापे समुपस्थिते | काषायवासा: कुछ्ठी वा पतितो ब्रह्म॒हापि वा
bhīṣma uvāca | cāṇḍālaśvapacau varjyau nivāpe samupasthite | kāṣāyavāsāḥ kuṣṭhī vā patito brahmahāpi vā |
毗湿摩说道：当供献丧祭饭团（piṇḍa）之时到来，应使旃陀罗（Caṇḍāla）与烹犬者（śvapaca）远离彼处。同样，在施行施罗陀（śrāddha）之际，博学之士亦规定：如披赭衣之出离者、患麻风者、堕落失德者，乃至杀害婆罗门者，都当从近旁移开，使仪式依律无碍而行，保持应有的清净。

Educational Q&A
The verse states a dharmaśāstra-style rule for ancestral rites: when performing nivāpa/piṇḍa and śrāddha, certain persons considered ritually obstructive (by traditional norms) should be kept away so the rite proceeds with prescribed purity and focus.
In Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma, including detailed conduct for śrāddha and offerings to ancestors. Here he specifies who should be excluded from the ritual space at the time of the offering.
