This question has been plaguing me last night, when I lay down on my bed just pondering.. After getting reincarnated countless times, after completing your lives mission in this world, after doing the same thing for millions of years until you're an old soul.. Where to next? Heaven? I have heard theories that you become angels and help God in Heaven, in another article. For Buddhism, you reach Nirvana and become a deity, but you'll come down to Earth occasionally to help others. But what do you think?
