What seems to us to be a whole life, the life of a person, is but a short step in the existence of our soul. In fact, the soul has been inserted in the Created to take a long journey in which to gradually understand itself and that which is created around it. This journey is implemented in physical existence, in many physical existences. These physical existences give the soul the experience that allows it to gain knowledge; in other words, to evolve: there is evolution only through the body’s experience. And the conclusion of this evolution is the return to the Creator.
