BhagavadGita fundamentally says that humans should do their "prescribed duties" with purified intellect, abandoning attachment to the fruits of their works, and dedicating them to God.
My question is what does "prescribed duties" mean? How do I differentiate between prescribed duties and unprescribed duties?
Some example situation: Suppose one of my good friend ask for help but due to the busy nature of my work, I am not able to help him. Am I not doing my prescribed duty.
There are lot of similar situation when I get confused.
Can somebody throw some light on the matter?
