कर्मण्येवाधिकारस्ते

कर्मण्येवाधिकारस्ते मा फलेषु कदाचन।
मा कर्मफलहेतुर्भूः मा ते संगोऽस्त्वकर्मणि ॥  (गीता)

Meaning: Your domain is action, not its results. Do not consider yourself fully responsible for the results or do not act with a belief that you will surely obtain the results commensurate to your action; nor should you therefore shrink or run away from doing your work (on account of uncertainty with which the results show up).

Interpretation: What, perhaps, Krishna wants to tell us that in between the doer's action and the results there is a long chain of other conditions. Since the cause (scholastically described)  of the result is all the negative and positive conditions taken together - the collocation and the moving power -  (including the action directed to obtain the result), there is a stochastic (in a very general sense that includes all types of measurable and not-measurable uncertainty) or unpredictable relationship between action and the result. Results are in a stochastic (so to say) range with unknown probabilities and possibilities. Therefore, one should not arrogate upon oneself either bravado or the undue blame for success or failure. One should only concentrate upon the domain of one's action. Nevertheless, one should not indulge in inaction simply because the results are uncertain. 

In a lighter vein the equation that describes results with action is: Results = f(A) + f(E), where f(A) maps the action (A) to the results and f(E) maps the environment to the results. E contains many forces with unknown probabilities and possibilities (in a fuzzy sense and a content of ambiguity and fundamental uncertainty). There are no well-known procedures to find expectations (of results).
Under this situation, the doer cannot solely be responsible for the results. However, if the doer does consider himself/herself so, either arrogating ego or a damaging discouragement will occur which would lead him/her astray.


I wonder what is there to disagree!
