This 46 minute lecture from Chabad.org is an in-depth exploration of some esoteric, historical and halachic ideas around the Grace After Meals by Rabbi Yehuda Leib Schapiro, the dean of the Yeshiva Gedola Rabbinical College of Greater Miami, the Rabbi of Congregation Beis Menachem, and a community leader in Miami Beach, Florida. The lecture would be beneficial for those who already have some background of Jewish knowledge and are looking for a comprehensive and in-depth discussion about the many aspects surrounding this ritual.
