Every Jew anxiously awaits the arrival of Moshiach. Whenever we Daven or do Mitzvos, we have special Kavanah that it should help bring Moshiach. On the Shabbas of Tazria - Metzorah 5751, the Rebbe told Klal Yisroel - that although every Mitzvah brings Moshiach - that there is a "Direct Path" to bring Moshiach. This path is: Learning the subjects of Moshiach that are explained in the Torah! Following this directive, Yeshivas Lubavitch Cincinnati has a daily Shiur in Inyonei Moshiach and Geulah, given by Rabbi Gershon Avtzon. The Shiur - although short - covers a different topic every month. The Shiurim are recorded by the students and then made available to the public.
There are 11 different topics available - so far - and are divided into four series (see CDs). Each CD - topic - can be bought separately or downloaded for free! Beware: You will get inspired!!
