The concept of Torat Eretz Yisrael is not some new invention. For example, the Midrash states: “’The gold of this Land is good’ – this comes to teach us that there is no Torah like Torat Eretz Yisrael” (Bereshit Rabbah 16:4). Also, “If you want to see the Shechinah in this world then occupy yourself with Torat Eretz Yisrael” (Shochar Tov, Tehillim 105). “The air of Eretz Yisrael promotes wisdom” (Baba Batra 158B).
