When we think about Yom Tov, we tend to associate a specific Yom Tov with its unique Mitzva (Rosh Hashana-Shofar, Pesach-Matza etc.)Other than cheesecake (which, funny enough is not listed in the Mishna Berura) why does Shavuos not have a Mitzva of its own.
R’ Moshe Feinstein says that there actually is something unique to Shavuos. THe korban of Shavuos, the Shtei HaLechem is the only koban brought which is chametz.
What is the significance of this and why would we bring a korban of Chametz after we just removed all our chametz for pesach?
Granted that during Pesach we view the chametz as the Yetzer Hara, and therefore we rid ourselves from it. But chametz also represents gashmius. During the holiday of Shavuos, the chag of Kaballas HaTorah we specifically bring a korban of gashmius to show that Torah is all encompassing in all aspects of our life. The Torah is not just for ruchnius, it teaches us much more. Therefore we go out of our way to bring the most gashmius of korbanos to show our recognition and thanks to HaKadosh Baruch Hu for this all encompassing Torah which guides us though our daily challenges.
