What does Bhagavad Gita teach?

What does the Bhagavadgita teach? You are free to act or not to act or choose how to act. Work is your jurisdiction. But after performance the result falls into the jurisdiction of laws of nature. The result does not belong to your jurisdiction.

Every action ends in a result: this is a scientific truth. Therefore if a contrary or unexpected result comes it should not disturb your mind because the result is not in your hands. You should not internalize the situation by considering yourself to be a failure because the result is an objective reality. Failure or success is a subjective perception. It is also affected by so many other factors like karma, which are simply beyond you. All you are expected to do, as an effective manager is work sincerely giving importance to minute details and with perfect concentration. This demands the practice of meditation which is yet another contribution of Indian philosophy. Concentration the mind eliminating any disturbing thought while you are in your workplace.
