Ma phaleshou kada chana-
“You have the right to perform your actions, but you are not entitled to the fruits of the actions.”
Ma Karma Phala Hetur Bhurmatey Sangostva Akarmani–
“Do not let the fruit be the purpose of your actions, and therefore you won’t be attached to not doing your duty.”
As an example:
“A student –
His duty is to study, he passes or fails that’s not in his control. The student does not study just for the sake of passing his exams. When he studies, he learns. Whether he pases or fails he should not be too happy or too sad about it.
If ever a student studies for the sole purpose of passing his exams, in the end he has not learned anything even if he has passed. But if he studies because he considers learning and studying as his duty, he won’t even need to be worried whether he will pass or fail. And such a student as we have always seen they are most likely to pass their exams. Unless they are not able to reach their exam for some reason. But still he should not be sad about it. Why? Because the most important is at least he performed his duty well.”
We can also relate this to selflessness:
When we help someone, we don’t do it for the sake of something in return, whether we are rewarded for our actions or not, this is not our concern. And when we help someone without worrying about our own gains, this is selflessness. We don’t think what are we going to get from that. The importance is that as a human being we have been able to help someone.
