Resettlement of Souls

Do you believe that the soul can move after death? And that the soul even exists? Perhaps the toucan was once a girl or an elephant. Why not believe when you look into the eyes of a dog for example, which has a very understanding, open, pitiful and native look, which knows everything ... And when you look into the eyes of a man, and there is nothing, cold and angry look, in which there is not a bit of emotion, as if you are looking into the eyes of a shark .
