It's hard to believe in this wide universe that there is only one chance to live in a lifetime. There are many controversial issues surrounding the subject of reincarnation.
Reincarnation is to be reborn as another individual, usually someone different from the one before.
Though most souls reincarnate, not everyone is reincarnated. Reincarnation is a select process for the role the person will have to live. A person may reincarnate immediately after death, or may be assigned to a dimension of life, which is a plane before heaven, until it is time for the person's reincarnation. Reincarnationists believe that most people can reincarnate many times, due to an ongoing goal, or to initiate important decisions that would insure the future of the world. Even Jesus Christ is mistaken to be a messiah from another life, when He had a spirit life prior to incarnation.
