Varṇasaṃkara: Causes, Classifications, and Conduct-based Recognition (वर्णसंकरः—हेतु-जाति-आचारनिर्णयः)
ददाति हि स पिण्डान् वै पितुर्मातामहस्य च । पुत्रदौहित्रयोरेव विशेषो नास्ति धर्मत:,दौहित्र अपने पिता और नानाको भी पिण्ड देता है। धर्मकी दृष्टिसे पुत्र और दौहित्रमें कोई अन्तर नहीं है
dadāti hi sa piṇḍān vai pitur mātāmahasya ca | putra-dauhitrayor eva viśeṣo nāsti dharmataḥ ||
Bhishma said: “Indeed, he offers the piṇḍas (funeral rice-balls) to his father and also to his maternal grandfather. From the standpoint of dharma, there is no distinction between a son and a daughter’s son.”
भीष्म उवाच
Bhishma teaches that, in dharma, a daughter’s son (dauhitra) is not inferior to a son regarding ancestral obligations: he can perform śrāddha duties such as offering piṇḍas, including for the maternal line.
In the Anuśāsana Parva’s instruction on dharma, Bhishma lays down a rule about ritual responsibility and kinship: the dauhitra offers piṇḍas to his father and to his maternal grandfather, showing parity between son and daughter’s son in religious duty.
