Shiur from Rabbi Elimelech Kohn Ztl on פרשת שמיני . 
Discussed:

Understanding the concept behind Korbonos, and why Ahron brought a Korbon Chattas for himself and a Korbon Olah for Klal Yisrael to atone for the חטא העגל (sin of the Golden Calf).
The Malbim writes that each person represents a mini-Mishkan. Man's Avoda is to sacrifice his animalistic nature, paralleling the Kohen's Avoda in the Bais Hamikdash.
The Kli Yakir explains, based on a Medrash, how Machlokes and jealousy (מכירת יוסף) lead to Avoda Zara (חטא העגל).
