Reincarnation is a belief in the eternal validity of the soul.
You live a specific life, you learn a much needed “soul lesson,” or you might develop a talent, a skill, or learn to love. And then you die. Once you die, you get to look back on the life you’ve just lived, and you decide how you did. You’re either pleased or proud, or you might be annoyed and disappointed.
Then you go to the “In Between,” a Buddhist concept, where you’re greeted by your own soul group. Each soul group has an overall purpose, and every person has a specific purpose.
The movies “Defending Your Life,” and “Heaven Can Wait,” are just two of the many American movies that posit a belief in reincarnation.
