what “ir” said is quite tue, regarding Sinos Chinam.
I’m sure you all know the song “I am an ancient wall of stone. . .” My favorite line from that song is the following: “HOW CAN YOU COME BACK HOME TO ME, WHILE YOU REMAIN APART?” I don’t know who wrote the song but that line is so, so true. How can we even think that the Bais HaMikdosh will be rebuilt as long as “SINAS CHINAM IS STILL THERE, IT LINGERS IN YOUR HEART. . .” How many of us get upset over the silliest things at work, at home, at school, in camp, on the road. . . And yes, the feelings we feel are Sinas Chinam- hatred for nothing. Just let it pass. The most important thing here is to Fargin and let bygones be bygones.
(By the way, I don’t mean to talk directly to anyone in the CR or reading this, this post is more for myself than anyone else.)
