There are degrees in many worlds, and there are souls which receive from degrees they are at. We do not feel this, but these souls are within us. Our task is to reveal them, to reach a state when we ourselves would control the level of our souls. Therefore, it is very important to achieve a sensation of souls and worlds, in order to understand the course of actions to raise our souls along the steps of the worlds and thus perceive the universe at an increasingly deeper level.
