संकरो नरकायैव कुलघ्नानां कुलस्य च ।पतन्ति पितरो ह्येषां लुप्तपिण्डोदकक्रियाः ॥
saṃkaro narakāyaiva kulaghnānāṃ kulasya capatanti pitaro hyeṣāṃ luptapiṇḍodakakriyāḥ
This confusion leads to hell the ruiners of the family, and the family; for their ancestors fall, deprived of piṇḍaḥ (rice offering) and libations.
