You should never impart this knowledge to those who are devoid of austerities or devotion, not even to those who do not desire to listen, and to those who find fault with Me as well.

भगवद्गीता– अध्याय १८, श्लोक ६७

इदं ते नातपस्काय नाभक्ताय कदाचन |

न चाशुश्रूषवे वाच्यं न च मां योऽभ्यसूयति ||

अनुवाद: तुम्हें यह ज्ञान उन्हें कदापि प्रदान नहीं करना चाहिए जो तपस्या या भक्ति से रहित हैं, न ही उन्हें जो सुनने की इच्छा नहीं रखते हैं, और उन्हें भी नही जो मुझमें दोष देखते हैं।

You should never impart this knowledge to those who are devoid of austerities or devotion, not even to those who do not desire to listen, and to those who find fault with Me as well.
