What is the 50-year Yovel counting cycle about? The commandment of counting the 50 yeras helps guide us toward the implementation of freedom and equality for all - not only in the Sabbatical (Seventh "Shemitta" year) and Yovel (Jubilee) year, when the Torah commands that land and people shall be released, but that throughout the cycle, we should be helping people to stand on their own two feet.  

What is important about he Shemitta and Yovel cycle is not only whether the land lies fallow, but whether the social justice system behind the "Shabbat of the years" is being fulfilled. If that system is failing to be fulfilled, mass exile will be the consequence (as detailed in Yirmiahu's castigating those who freed the slaves -but then immediately forced them to return).

It is only on the basis of social justice that the Mikdash and its significance can survive - and we can dream of the restoration of Jerusalem's former glory only if we build a just and kind society.
