Every word of torah is the embodiment of the greater light of Hashem. Even the Germans recognized the holiness of the Talmud. The light of Hashem can only descend through the Jewish nation. Torah L’shama (for God’s sake) is learning with an awareness that there is a light contained within each letter. This awareness hastens the redemption. The letters and vowels in Torah are visible, however the light of the Torah is ayin (nothingness). We have to connect ourselves to the ayin. Torah L’shma will definitely bring a person back to Hashem.
