Jiva or Living Entity: Falldown of a Jiva

                                                                  Q. I have read in many places about the phrase 'fall down'. I am a bit confused about what is the meaning of fall down of a devotee?

                                                                  What does it actually mean when we say a devotee (both a neophyte and a elevated devotee) has fallen down? When can I consider that I have fallen down? Is it that when we deviate from the instructions of the spiritual master in a broader sense, or is it when we break any regulative principle; or is it both, or is it anything else? A Pure devotee cannot fall down (by Krishna's Grace). For aspiring devotees like us, since we are not pure, we are anyways fallen. So how can we identify that event of fall down  and take a recourse action to reinstate ourselves?

                                                                  Q: If the soul is part and parcel of Krsna (BG 15.7) and given Krsna is in the spiritual world and everyone in the spiritual world is infallible (BG 15.16), how is it that the soul has fallen into the material world in the first place?
                                                                   
                                                                   
                                                                  As Krishna's extended parts and parcels, the jiva has qualities like Krishna. One of those qualities is free will. Krishna has unlimited free will, whereas the jiva has tiny free will.
                                                                   
                                                                  When utilized properly, the jiva's free will is lovingly directed towards Krishna's service and seeking His happiness.
                                                                   

                                                                  Q: From Science Of Self Realization book, below paragraph convinced me of why we should surrender and go Back to Krishna

                                                                  “The beginning of our present material life cannot be traced, nor is it necessary for us to know how we became conditioned in material existence. We have to be satisfied with the understanding that somehow or other this material life has been going on since time immemorial and now our duty is to surrender unto the Supreme Lord, who is the original cause of all causes”

                                                                  But From BG 8.3  in the last paragraph of the Purport it says
