Bhagavad Gita 1.44
उत्सन्नकुलधर्माणां मनुष्याणां जनार्दन। नरकेऽनियतं वासो भवतीत्यनुशुश्रुम॥
utsanna-kula-dharmāṇāṁ manuṣhyāṇāṁ janārdana narake ‘niyataṁ vāso bhavatītyanuśhuśhruma
Translation
The abode of the men whose family customs are extinguished, O Janârdana, is everlastingly in hell. Thus have we heard.
What it means
"We have heard" that destroyers of family customs dwell in hell. Hearsay closes his argument. Krishna's method in chapter 2 will be the opposite: not what is heard, but what can be known about the self, duty and action.
Try this today
'Thus have we heard' - he is quoting inherited belief, not verified knowledge. Distinguish what you know from what you have heard.
Something to reflect on
Which of my strongest fears are second-hand beliefs I never examined?
