Bhagavad Gita 2.47
कर्मण्येवाधिकारस्ते मा फलेषु कदाचन । मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥
karmaṇy evādhikāras te mā phaleṣu kadācana | mā karma-phala-hetur bhūr mā te saṅgo 'stv akarmaṇi ||
Translation
Your right is to action alone, never to its fruits. Let not the fruit of action be your motive, nor let your attachment be to inaction.
Reflection
What in your week were you doing in order to, that you could be doing simply because?
Read this verse in its chapter: Chapter Two
The verse the entire tradition rests on. Four clauses, each a refusal of an exit. Adhikāra (right, claim) lives on the side of action, not on the side of fruit. The fruit is not yours to hold; the doing is. The third clause closes the trapdoor: do not become the fruit-driven cause of action. Do not act in order to. The fourth closes the other trapdoor: do not get attached to inaction either. Krishna is not telling you to be indifferent to outcomes; he is telling you not to anchor your motive there, and not to anchor it in withdrawal either. The middle stance is what the chapter has been building toward.
