In this shiur, delivered in Ba'er Miriam, Rav Burg explains the inner meaning of the Niddah cycle. The halacha of the mother who gives birth to a baby boy and gives her son a Bris represents the Torah of man. We are not meant to live in a state of Tahara but to achieve a state of Tahara. In this way we rectify the sin of Adam HaRishon.
