कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि।।2.47।। karmaṇy-evādhikāras te mā phaleṣhu kadāchana mā karma-phala-hetur bhūr mā te saṅgo ’stvakarmaṇi Your business is with action alone; not by any means with fruit. Let not the fruit of action be your motive (to action). Let not your attachment be (fixed) on inaction.
