Rabbi Yisrael Lipkin of Salant


Man must give priority to the soul over the body with respect to himself; but must not overlook the body where someone else is concerned, since the next person’s physical [gashmiyus] are his spiritual [ruchnius] affairs.
From Tenuas HaMussar (The Mussar Movement)


For an excellent treatment of this topic, I happily suggest taking a look at R Micha Berger’s post, here.
