Attributes of Krishna: Krishna - The Cause of All Causes

                                                                  Q. 1.  Lord Krishna is explaining in 10th chapter that he is the creator of everything. I have serious doubts of who is the doer.

                                                                  BG 10.2: Intelligence, knowledge, freedom from doubt and delusion, forgiveness, truthfulness, control of the senses, control of the mind, happiness and distress, birth, death, fear, fearlessness, nonviolence, equanimity, satisfaction, austerity, charity, fame and infamy — all these various qualities of living beings are created by Me alone.

                                                                  Q. In the Gita verse 2.47 ("Never consider yourself to be the cause of the results of your activities..."), does it mean that we are not the producers of our results? Does the sanskrit word "hetuh" = "cause"
                                                                  essentially mean the "producer" or does it imply something else?

                                                                  Yes,  BG 2.47 says precisely what He means to say: the jiva is not the cause of the results of activities.

                                                                  Please carefully read BG 5.14

                                                                  Q. In Bhagavad-Gita 2.47, Lord Krishna says, "You have the right to perform your prescribed duty, but you are not entitled to the fruits of action. Never consider yourself the cause of the results of your activities, and never be attached to not doing your duty."

                                                                  Question a) In this world activities are performed with the results in mind and in fact the results are the motivation for one to do work. How does one perform his
                                                                  activities in this world without expectation of fruits / results?
