Our believe or disbelief does not change the truth, and the truth is reincarnation exist, life is a school and so many people cannot pass this school at the same time, so the opportunity is given for amendment through the process of reincarnation. It is not a diabolic process as most people think, but it is an opportunity given to us, but the best appreciation we can show is to live a meaningful life while here on earth, just like a good student studies diligently to avoid repeating his or her class.
