CHAPTER 1 · VERSE 41
Bhagavad Gita 1.41
सङ्करो नरकायैव कुलघ्नानां कुलस्य च। पतन्ति पितरो ह्येषां लुप्तपिण्डोदकक्रियाः॥
Chaos leads both the destroyers of the family and the family itself to hell. Their ancestors fall as sacred offerings of food and water cease.
Arjuna worries about spiritual consequences when ancestral rites can no longer be performed.
