Actually, I've heard it described as being similar to reincarnation by many people -- just none of them LDS. I honestly don't know all that much about reincarnation, so it may be more similar than I've always thought. I think the main thing to understand about Mormon theology in this regard is that we believe the human spirit is eternal. Yes, it was created by God, but the material from which He created it has always existed. So, the next point is that the spirit is the essence of life. It can exist within the confines of a physical body, but it does not need to. The thing is that the spirit itself never really changes. Its attributes are pretty much constant over time. We believe that each of us started our existence in spirit form, came into this world as mortal beings at birth, at which time the spirit that had previously been living in God's presence entered into the physical body giving it life. At death, the individual's brain functions cease and the physical part of us dies. The spirit, however does not die, but continues to exist as a fully cognizant entity at that point and resides in an intermediate realm -- neither Heaven nor Hell -- until the resurrection, when it re-enters a newly perfected and immortal body, never to leave it again. That new body, however, is still essentially the same in appearance as it was during mortality (in other words, I would be recognizable to people who knew me here). The body is different in that it is no longer subject to aging, disease, deformity or death. If I understand reincarnation correctly, someone can live one life as a worm, another as a frog, another as a chimpanzee (I threw that in there just for you) and another as a human. This would be impossible according to Mormon thought. I was "me," Katzpur, during my premortal existence (before I had a mortal body). I am "me," Katzpur, now, complete with my totally imperfect body and all. I will be "me," Katzpur, after my spirit leaves my body after my body stops working completely, and I will be "me," Katzpur when I have a new, immortal body where the very same spirit I possessed during my pre-mortal life will reside forever.
