2.47
श्रीभगवानुवाच
कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि॥
Your right is to action alone, never to its fruits. Do not let the fruit of action be your motive, and do not be attached to inaction.
You have a right to the work, never to the fruit. This is the Gita's most practical medicine for ambition, burnout, and comparison.
2.48
श्रीभगवानुवाच
योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनञ्जय। सिद्ध्यसिद्ध्योः समो भूत्वा समत्वं योग उच्यते।।2.48।।
Revised: Perform all your actions with your mind concentrated on the Divine, renouncing attachment and looking upon success and failure with an equal eye. Spirituality implies equanimity.
3.8
श्रीभगवानुवाच
नियतं कुरु कर्म त्वं कर्म ज्यायो ह्यकर्मणः। शरीरयात्रापि च ते न प्रसिद्ध्येदकर्मणः।।3.8।।
Do your duty as prescribed, for action for duty's sake is superior to inaction. Even the maintenance of the body would be impossible if one remained inactive.
3.19
श्रीभगवानुवाच
तस्मादसक्तः सततं कार्यं कर्म समाचर। असक्तो ह्याचरन्कर्म परमाप्नोति पूरुषः।।3.19।।
Therefore, do your duty perfectly, without worrying about the results, for he who does his duty without attachment attains the Supreme.
3.30
श्रीभगवानुवाच
मयि सर्वाणि कर्माणि संन्यस्याध्यात्मचेतसा। निराशीर्निर्ममो भूत्वा युध्यस्व विगतज्वरः।।3.30।।
Therefore, surrender your actions to Me, keep your thoughts focused on the Absolute, free from selfishness and without expecting a reward, with a mind free from excitement, begin to fight.
4.18
श्रीभगवानुवाच
कर्मण्यकर्म यः पश्येदकर्मणि च कर्म यः। स बुद्धिमान् मनुष्येषु स युक्तः कृत्स्नकर्मकृत्।।4.18।।
He who can see inaction in action, and action in inaction, is the wisest among men. He is a saint, even though he still acts.
18.45
श्रीभगवानुवाच
स्वे स्वे कर्मण्यभिरतः संसिद्धिं लभते नरः।स्वकर्मनिरतः सिद्धिं यथा विन्दति तच्छृणु।।18.45।।
Perfection is attained when one diligently attends to their duty. Listen, and I will tell you how it is attained by one who always minds their own duty.
18.47
श्रीभगवानुवाच
श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।स्वभावनियतं कर्म कुर्वन्नाप्नोति किल्बिषम्।।18.47।।
It is better to do one's own duty, however defective it may be, than to follow the duty of another, however well one may perform it. He who does his duty as his own nature reveals it, never commits a sin.
