Bhagavad Gita 2.47

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन।मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि॥

karmaṇyevādhikāraste mā phaleṣu kadācana |mā karmaphalaheturbhūrmā te saṅgo'stvakarmaṇi ||

Your right is only to work, but not to its results; do not let the results of action be your motive, nor let your attachment be to inaction.

But you have only the right to work, but none to the fruit of it. Let not the fruit of your action be your motive; nor be you enamored of inaction.

Our plain-language meaning of this verse is waiting for scholar review.
