I was onces told by a old folk on this.........Life here on earth is a prison of another world.
You had done something wrong over there and posted to here......that's mean you have to suffer here in life....work, stress, hunger, illness.......etc. And if your behaviour and conduct is good, then 'they' will release you back to the another world.....or else you will con't to stay here and suffer. Sometimes you can see why good people have short life and bad people have longer..........hmmmm....I just wonder how true.
