Shiur from Rabbi Elimelech Kohn Ztl on פרשת פקודי, continuing on the topic of the Yetzer Hara. Can be listened as a standalone Shiur. 
Discussed:  

The Rambam in his Hakdama to Mishnayos asks, what is the value of all the people who waste time and spend their days in trivial pursuits? 
The Paradox of money: Why people have a limitless desire for money, a means to an end, but the end (physical pleasure) is very limited.  
The Gemara Darshans the Pasuk אוהב כסף לא ישבע כסף (he who loves money will never be satisfied with money) to refer to Moshe Rabeinu.
