The term "Torah lishma" has sparked a deep controversy between Chassidim and Misnagdim. What is the essence of studying Torah? Torah is revelation of G-dliness. Reb Menachem Mendel of Vitebsk recruited many outstanding scholars for the Maggid of Mezeritch. There is a big "disconnect" between learning Torah and living Torah. Purpose of learning Torah is to be attached to Hashem. Both the Baal haTanya and Reb Chaim of Volozhin wrote important seforim addressing the very important issue of loss of feeling of dveykus (attachment) to Hashem.
