Are we rewarded or punished for our actions?

There is no reward or punishment for our actions, it is only consequences. Or there is an external force which decides rewards and punishments.

Is there any external agency which rewards or punishes us? In our eyes they may seem to be rewards and punishments , actually they may be just consequences. Not necessarily every good act is rewarded and a bad one punished. Do you believe in concept of heaven and hell after death? Yes, if we do good generally as a consequence good things happen to us most of the time but not always and vice versa.
