our soul does not die but lives on in the next generations, that's why genetics is important, and in a strong family, through sperm, the human soul moves on and you don't die, and your life's work continues in the next generations, that's why each of us has some desires and already in previous lives some stronger directions, that's why royal families build empires that they don't actually die, but through sperm they can continue to live and develop the work and activities of their ancestors.
So that's how actually the incarnation of the souls works that's why the royal families want to inter marriage to hold same type of souls and dna together trough history.
