From that particular point I few the world I might say that we all already have lived in many different centuries, several times. But the very most have forgotten it. And this oblivion has an reason.
But what could be better for our lifes if we just change the place, the loved ones, the car, the work etc. without changing ourselves? Wouldn´t we just carry all our heavy baggage with us?
I think we´re not here to run away. I think we´re here to learn handling our emotions. And we´re still here because we havn´t got it in the other centuries where we also had the chance to.
