Intro given 10/30/2023 by Rabbi Mendel Kessin This shiur (class) was given before Tisha B'Av in 2002. It was recorded and distributed by the Chofetz Chaim Heritage Foundation (https://cchf.global/). It was then re-distributed by Or Ganuz (https://www.concealedlight.com/) Afterword by Harav Shmuel Kamenetzky, Shlit"a Due to the current Middle East conflict and the protection Shmiras Halashon (watching what you say) can bring, Rabbi Kessin has decided to re-post this shiur.
