Reply To: The world is in a state of Geula- and don’t misunderstand us!

Laskern The Rebbe analyzes the various sources and comes up with four options:
1) we build what we can led by moshiach, and Hashem will add whatever isn’t clear (the changes in nevuas yescheskel.)
2) Moshiach will put up the doors to the BHMK that Hashem will build, as putting up the doors is like building the whole thing.
3) Moshiach will build the physical BHMK and Hashem will send down the spiritual one and they will fuse together.
4) it depends on our spiritual level. If we’re on a lower level, then moshiach will build it (halacha anticipates worst case scenario hence the Rambam). If we’re on a higher level than it will be revealed from heaven.
