We are capable of understanding the revealed Torah- letters, vowels, taamim (cantillation), and tagim (crowns). The hidden Torah is “ayin” (nothingness). Every letter of Torah has a tune. Why are there so few gedolim (Torah giants), when there are so many men learning? We have to try to and daven to connect to the hidden light of Torah. The hidden light of Torah is the “ohr haganuz” (hidden light) saved for the tzadikim (righteous ones). Only the hidden light of Torah can return us to Hashem.
