Menachem
As soon as klal yisroel starts doing what you wrote that most of us today are sadly lacking and it’s the most important part of helping bring Mashiach speedily in our days.
Were missing the YEARNING FOR MASHIACH. Lets all be honest…. Were so happy in this Tesla and technology world Golus generation were living in today. Would we be ready to give it all up completely this minute?
If klal yisroel was really mourning for the bais hamikdosh then we would be willing to fast a full extra day from the end of the fast of Tisha bav which is for mourning the bais hamikdosh
