Why so much emphasis on the laws of Kashrut? In this shiur we will study the insights of the Ramban, the Ari, the Vilna Gaon and the Seforno on the spiritual impact of the eating of non-kosher animals and birds. We will also analyze the relationship between the sin of the golden calf and the dietary laws, as well as the relationship between the dietary laws and the day of the dedication of the Mishkan - Rosh Chodesh Nissan. We will map out three major moments in Jewish History: Har Sinai, the dedication of the Mishkan, and the ultimate redemption. What is the relationship between the people of Israel and the Divine Shechina at each of these moments?
