इदं ते नातपस्काय नाभक्ताय कदाचन |
न चाशुश्रूषवे वाच्यं न च मां योऽभ्यसूयति || 67||
idaṁ te nātapaskyāya nābhaktāya kadāchana
na chāśhuśhruṣhave vāchyaṁ na cha māṁ yo ‘bhyasūtayi
BG 18.67: This instruction should never be explained to those who are not austere or to those who are not devoted. It should also not be spoken to those who are averse to listening (to spiritual topics), and especially not to those who are envious of me.
