Ar'a D'Yisrael B'Galuta / ספר ארעא דישראל בגלותא

An extensive halachic and philosophical treatise exploring the spiritual concepts surrounding the expansion and presence of the holiness of the Land of Israel (Kedushat Eretz Yisrael) within the Diaspora (Chutz LaAretz). The author systematically evaluates classical talmudic sources, geonic responsa, rishonim, and acharonim to map out how the divine sanctity attached to the holy land projects onto Jewish synagogues, communities, and study halls globally throughout the historical exile.
