When someone walks the street and thinks words of Mishna or Tanya, or sits in his store with a Chumash or Tehillim – that is more valued today than it was when the streets were bright with the light of Torah. We must not go about in the street with a vacant heart. We must have some Torah memorized, to take with us into the street. ~ R’ Yosef Yitzhak Schneersohn zt”l
