Suffering: Suffering of a Devotee

                                                                  Q. Even after doing lot of pious activities, devotional services one still undergoes lot of suffering? Why?
                                                                  What is the solution? Good people go through bad things and Bad people go through good things? Why?

                                                                  Q. It has always been puzzling for me when, in the heat of life's struggles, one faces situations of hardship, how does one know if it is, for example, Krishna testing our resolve to serve him, or is it karma because our endeavor is contaminated by material desires or, is it a message meant to make us realize that adjustments need to be made in order to achieve our goals?
