Disconnection

Why is it that the human being feels so disconnected from him (or her) self? Why is it that he feels incomplete? So that he is always looking for something to fill himself up with. Before he has finished his lunch he is onto his dinner. Yet no matter how much he consumes he always seems to feel empty. Is it possible for the mind, body and soul all to be energetically in the same place at the same time? So that there is no rattling around. So that there is no distraction or movement away from present existence.
