Bhagavad Gita · 18.60

स्वभावजेन कौन्तेय निबद्धः स्वेन कर्मणा।कर्तुं नेच्छसि यन्मोहात्करिष्यस्यवशोऽपि तत्॥

svabhāva-jena kaunteya nibaddhaḥ svena karmaṇā kartuṁ nechchhasi yan mohāt kariṣhyasy avaśho 'pi tat

O son of Kunti, bound by your own karma born of your nature, that which from delusion you wish not to do, even that you shall do helplessly.
