High Court to Decide Amona's Mirror Image Arab Case
Where is The Mishkan?
Rav Menachem Mendel Mi'Kotzk answered that the Mishkan is wherever you want it to be. All you need to do is to make place for it. You need to create a Makom Kadosh. Once you do that Hashem will rest His Shechina anywhere, even in each individual person. That is what the pasuk says "V'Asu Li Mikdash"; make me a Holy place. "V'Shachanti Bisochum"; I will rest in them. "Them" is plural because Hashem's Shechina is not limited to a single place. It will dwell anywhere it is invited.
I heard in the name of Rav Ezriel Tauber that after the Holocaust, Moshiach was given permission to come down. The "satan" will not stop him anymore. The problem is that he has no place to come to. The satan works hard to make sure there is no "4 Amos" anywhere in the world completely clean of "tumah" to which Moshiach can come down to. Our job today is to create a sterile environment, clean enough to host Moshiach.
