The souls aren’t fragile, they are hard, more than the hardest diamond on Earth. It is simply a different kind of toughness. They have only one breaking line that divide in two identical parts its shape. After the long journey to reach the planets, when they touch the ground, then it splits in two half. Every part, bounces in a different direction until they find a new home. For the rest of their time in the new dwelling, they will search to rejoin to the other half. It can takes more than a human life. The half continue to move until that moment. That’s because when you fall in love we are so happy: all this unknown efforts finally find the only possible epilogue.
