In this shiur, Rabbi Dunner emphasizes the communal aspect of holiness, inspired by the Torah's command "Kedoshim Tiheyu" — "You shall be holy." The significance of this directive being delivered publicly to the entire Jewish community underlines the collective responsibility and effort required to achieve holiness. Rabbi Dunner integrates stories of Rav Samson Raphael Hirsch and the Chofetz Chaim, who uplifted their communities by embodying and teaching these values, demonstrating that true holiness is achieved not in isolation but through communal harmony and shared spiritual goals.
