Shiur from Rabbi Elimelech Kohn Ztl on פרשת ויקהל, discussing the Yetzer Hara.  
Discussed: 

The meaning of במראת הצבאת (mirrors of the legions) that were donated for the Kiyur. Are we praising the women for spurning mirrors and physicality or lauding them for utilizing the mirror?  
R' Shamshon Refael Hirsch's question: Why did משה accept the women's jewelry including the כומז but (initially) rejected the mirrors used for the כיור.  
Two ways to understand what the Gemara means, "I created the evil inclination, and I created the Torah as a Tavlin".
