Bhagavad Gita 1.44

उत्सन्नकुलधर्माणां मनुष्याणां जनार्दन।नरकेऽनियतं वासो भवतीत्यनुशुश्रुम॥

utsannakuladharmāṇāṃ manuṣyāṇāṃ janārdana |narake'niyataṃ vāso bhavatītyanuśuśruma ||

We have heard, O Janardana, that those men in whose families the religious practices have been destroyed are inevitably destined to dwell in hell for an unknown period.

The wise say, my Lord, that they are forever lost whose ancient traditions have been lost.

Our plain-language meaning of this verse is waiting for scholar review.
