When i mean reincarnation, i mean dying and then being born again in a different lifetime. now when i mean karma, i dont mean that what i do today, lets say hit somebody will effect me tomorrow and cause me to lets say get this shit beat out of. i mean that say i kill someone in this life time, then i will be born into a bad environment in my next lifetime, or that if i save someones life, then i will be reborn into a better environment in my next lifetime.

My corporeal self will continue to exist after death, just as parts of other things. The things I have done in life will continue to resonate as the world will always be slightly different for me having existed. And any good I do will hopefully change things even an iota for someone else and kindness echoes for eternity.
Although Shakespeare posits an alternative version of the same thing. He wrote: "The evil that men do lives after them, the good is oft interred with their bones".
Also, I believe in karma, but not that it affects you in a different lifetime. Kinda like, if you do something bad in this lifetime, and don't make up for it, you'll be punished in this same lifetime. And in your new life, you can start with a clean record.
Reincarnation, too. Again, my personal belief system allows me to think that God takes on many forms for others to understand. I don't believe in reincarnation of the same soul per say, but I do believe in guardian angels and past lives. They may just be one in the same.
I also believe that when we die, we go somewhere else, not Heaven, but somewhere. I don't know where because I have obviously never been there, but I believe we don't just die and everything goes black. I wouldn't think we'd remember our past lives, I just believe we go somewhere else when we die. We might not even have past lives, and just go to some heaven-like place. I just don't believe in heaven.
God values human life, like his son Jesus, he wouldnt let our "souls" just wander around until it gets a new body. What does "Rest in Peace" even mean if you arent put to rest?
i highly doubt that anybody is the reincarnation of Jesus or else theyd have the best life possible since durning his life hes been spit upon and done many great deeds. ex "Good Karma" ; if you believe in it.
The Buddha is supposed to have had three constant pains throughout his life. Backpain (for physically abusing his mother in a past life), a headache (for being sadistic and enjoying the death of a fish that was dying slowly due to the lack of oxygen in a past life) and some other constant pain that I forget...maybe a stomach ache for something equally crappy.
This gives me hope if karma is in fact a reality. If someone who reached enlightenment had all this karmically playing on him even during that purified lifetime, then we aren't so bad off are we?
Then I was invited to a Christian church camp that was very passionate about God. On the long bus ride I sat by the wife of the pastor and while Christians do not believe in reincarnation I brought up the cases about how people reveal under hypnosis past lives and in turn are cured of their issues, & her answer was that it was like a dream. She had had a dream about owning a restaurant which was a total fantasy..
I was not satisfied with this explanation. I knew it didn't explain how people were cured and how it was consistent with their life long psychological affliction. My experience at the camp was extremely positive. Despite this inconsistancy, everybody was genuinely good natured, happy, loving, & accepting while being so passionate and determined to bring people to god. My assessment (in short but not exclusively from this experience) is that its not a "sin" to believe something that's not true.
As far as karma goes though, what they didn't teach me as a kid in Sunday school (my dad was Mormon. & used to take me when I was little sporadically) was that u don't do what's right just bcuz u owe it to God, but, by being a good person u have true happiness. It has been that way for me anyway. Just like how "God" is all knowing and good at the same time, like a mathematical proof. Being good is the smartest thing to be bcuz its the only way to true happiness.
