Want to know why Mashiach is not here yet? Just look at the Sium, I was so lucky to attend. How much pure Nachas does HaShem get, bli ayn hora so many Yidden, all together davening, answering Kaddish. All the ##,###(!!) of Yidden all there for one purpose alone, to be Mekadesh Shaim Shamaim, and give honor to HaShem's holy Torah. All the multitudes (kain yirbu) Mesaymim, most of whom are in the work force, the Galus Yid etc. using spare minutes, hard earned minutes to join a shiur, chabura, chavrusa. How much pure, unadulterated joy does HaShem get from this!! This is one thing that's going to missing when Mashiach comes - the struggle and Nachas of the Galus yid. Whether struggling to learn despite his career, financial difficulties, any other Galus-driven Yetzer Haras - it's so precious to HaShem.
I felt so good sticking in my pudgy little nose into, and joining, the (??,???) Yidden who were Menachem the Ribono Shel Olam, a mere few days after Tisha b'Av, in the BEST WAY POSSIBLE!!!
