Bhagavad Gita Chapter 3 Sloka 41 (3.41)

ತಸ್ಮಾತ್ ತ್ವಮಿಂದ್ರಿಯಾಣ್ಯಾದೌ ನಿಯಮ್ಯ ಭರತರ್ಷಭ ।
ಪಾಪ್ಮಾನಂ ಪ್ರಜಹಿ ಹ್ಯೇನಂ ಜ್ಞಾನವಿಜ್ಞಾನನಾಶನಮ್ ॥೪೧॥
tasmāt tvamiṃdriyāṇyādau niyamya bharatarṣabha |
pāpmānaṃ prajahi hyenaṃ jñānavijñānanāśanam ||41||
Gist of the sloka:
O the warrior from Bharatha dynasty, controlling the senses, being aware of the right and wrong, thinking clearly and deeply and not allowing it to be colored, drive away this sinner.
Explanation:
We should destroy this sinner at the very beginning. We should control this sinner at the entry level in the senses. This sinner destroys our knowledge [gynana - hearing] and science [vignana – imbibing and thinking capacity]. This great sinner should be driven far away. Lord Krishna tells us how and who can do so in the next verse.
