I have slowly been making my way through some of R' Elchanan's ma'amarim and found an interesting thought in the name of the Chofetz Chaim. "Bara'si yetzer hara, barasi torah tavlin" means, says the C.C., that Torah is the only antidote to the yetzer hara.
R' Elchanan explains: Contrary to popular belief, the yetzer hara does not really mind if you do mitzvos. What community does not have a bikur cholim, a chessed fund, tzedaka organizations, etc.? And people give time and effort to these projects! The reason why it is so easy to dedicate time and effort to these causes is because the yetzer hara does not mind. But, when it comes to talmud torah, the yetzer hara is on guard; the yetzer knows that only talmud torah can bring his downfall. Someone who truly devotes himself to torah study [and I assume he means a regular guy, not someone in kollel who has nothing else to do] is a rare trasure and an uncommon sight even within our frum communities.
