Rav Itamar Shwartz, Shlita, the author of the Bilvavi Mishkan Evneh seforim, is at the completion of a speaking tour in the eastern United States. He gave 14 shiurim at Litvishe Yeshivos, Sephardi Yeshivos, Chassidishe Kollels, Modern Orthodox institutions, and everything in between. All 14 shiurim are available for download and some are available in streaming audio. Please enjoy the Torah and may it be the impetus for us to work on being mekarev ourselves to Hashem.
