Bhagavad Gita Chapter 3, Verse 36

अर्जुन उवाच | अथ केन प्रयुक्तोऽयं पापं चरति पूरुषः | अनिच्छन्नपि वार्ष्णेय बलादिव नियोजितः ||

arjuna uvāca atha kena prayukto 'yaṁ pāpaṁ carati pūruṣaḥ anicchann api vārṣṇeya balād iva niyojitaḥ

Arjuna said: O Krishna, by what is a person impelled to commit sin, even unwillingly, as if driven by force?

After Krishna teaches about working with your nature and recognizing rāga-dveṣa as enemies (3.33-35), Arjuna asks the most honest question: 'Atha kena prayukto 'yaṁ pāpaṁ carati pūruṣaḥ anicchann api balād iva niyojitaḥ'—by what force is a person impelled to commit wrong action, even unwillingly, as if compelled? This captures universal experience: you know you shouldn't, you don't even want to, but you do it anyway. What drives you? Krishna's answer in 3.37 will name the enemy: kāma (desire) and krodha (anger), born of rajas. Not external circumstances—the force within.
