Chayei Sarah - The Blessings of an Integrity Life

In this shiur, delivered at Sharfmans, Rav Burg gives over an idea from Rav Lopiansky shlit"a that reveals the inner nature of Bracha (blessed) and Arur (cursed) . Why is it that Avraham tells Eliezer that he is Arur? How is it that Hashem sends a message to Eliezer through Lavan that he is blessed?!? One who lives an integrity life becomes a conduit for blessing in this world.
