"[T]he mitzvah of Ahavas Yisroel, “Mitzvas asei le’ehov kol echad v’echad mi’Yisroel kegufo”, is a positive commandment to love every Jew in the same manner that we love ourselves. This mitzvah is a klal gadol ba’Torah (fundamental principle of Torah), and furthermore, it is the yesod...of our Torah, upon which the entire Torah is based." (source)
"His Ahavas Yisroel, his love of doing mitzvos and teaching others, and his love of Torah are something each of us can take to heart and try to improve on." (source)
