सङ्करो नरकायैव कुलघ्नानां कुलस्य च। पतन्ति पितरो ह्येषां लुप्तपिण्डोदकक्रियाः॥
sankaro narakayaiva kulaghnanam kulasya cha patanti pitaro hy esham lupta-pindodaka-kriyah
Translation
An increase of unwanted population causes hellish life for both the family and the destroyers of the family. The ancestors fall, deprived of their offerings of food and water.
Commentary
Arjuna extends his argument to the afterlife — destroyed families cannot perform ancestral rites, causing suffering even to departed ancestors. This reflects the deep Hindu belief in duty toward ancestors.
