To understand the interrelationships of all souls is to understand all of human history. Once the collective becomes fragmented, it never comes together again. We enter the World to Come as we are, with our minds, our consciousness. When the whole of Israel commit certain sins they lose their spirituality, and all the great power that should come from it is lost to the nations of the world. It is possible for the whole of Israel to reclaim this power through hardships at the hands of those other nations. The ones who are responsible for the spiritual destruction of the whole of Israel today are other Jews who sin and cause others to sin.
