Common Misconceptions: Falling from the Spiritual World?

                                                                  Q. I've read that if we go back to Vaikuntha after this life, we will never come back to the material world. I think I have also read (or heard) that we were in the spiritual world before, but we were thrown in this material world because we misbehaved. How can you say that we will never come back here again? (Maybe we will misbehave again.)

                                                                  Q. What is the source of envy which brought us to this material world in the first place? I asked this question in one of our Sunday program and the speaker told me that there is no answer to this question. This really surprised me because I was thinking that Krishna could still be the source of the envy but yet unaffected by it. Just like 'maya' for which although Krishna is the source He is not affected by it. Please clarify.

                                                                  Q. On one hand Krsna has promised us that if we reach Goloka Vrndavan through devotional process then we won't return to this world of birth and death and at the same time we all are in this material world due to our envy towards Krsna. Weren't we all originally residents of Goloka Vrindavan?

                                                                  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

                                                                  Q. 1. It is said that all souls are originally with Lord Krishna. Then how we came back to this earth? What is the assurance that the soul would go back to Godhead if the person performs bhakti towards Him.
