In his introduction to Sefer Bamidbar, the Ramban depicts the parallel between Mishkan and Sinai, in both the central episode is the revelation of Shechina. Although Sinai is revealed, it is temporary. Mishkan is concealed, yet permanent. The essence of the Mishkan is the Aron which houses the Torah, and with regard to Torah, our experience is one of awe & fear. In this shiur we will study the Aggada in Masechet Megila regarding one who lacks fear in his relationship to Torah, and the implication of this Gemara for our service of HaShem.
