Sefiras Haomer was originally a period of glory, as we counted from Yetzias Mitzrayim up to Matan Torah. Later in history, it became a period of mourning for the deaths of the students of Rabbi Akiva. These two facets of Sefirah are apparent in the difference of the Torah taught by Moshe Rabbeinu. Moshe Rabbeinu taught Torah to Bnei Yisroel in a time of open miracles, with the presence of Hashem obvious and clear. Rabbi Akivaâ€™s Torah was taught right after the Churban. when Hashem's presence is hidden from us. Through our learning of the Torah of Rabbi Akiva, in difficult times, Hashem should bring us to a time of the Torah of Moshe Rabbeinu, with His open glory.
