Answer: Because you hear about yourself, about your soul, about the way you can attain a whole eternal state, where life and death of your body have no effect on you, and where you will begin to feel that life is infinite and flows in a totally different manner than what you imagine today.
If we begin to gather, we will feel the transition to the next state, to the upper world, in the connection between us, because it is in the center of our mutual cooperation.
Just as astronomers say that there is a transition from one state to another in space, it is the same here. It is a unique transition, a transition from our world and an entrance to the next world.
