कर्मणयेवाधिकारस्ते मा फलेषु कदाचन।
मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि।
“You have a right to perform your prescribed action,but you are not entitled to the fruits of your action. Never consider yourself the cause of the results your activities,and never be associated to not doing your duty.”
From a cursory point of view, this looks like a very hard teaching, like a cruel employer telling the labourer to work hard without expecting any wages. But does God say that we should go on working and He will give us nothing? God is not a cruel master. The principle behind the obligatory duty incumbent upon every individual is the involvement of every individual in the structure of the universe, The whole universe is one single body, of which the limbs are the modes of prakriti, and of which the soul is the all-pervading purusha: yena sarvam idam tatam (2.17).
