"When you will go out to war on your enemies and you will see horses and chariots, a multitude greater from (than) you, do not fear them for Hashem your G-d is with you, who took you out of the land of Mitzrayim. And when you will come close to the battle... etc...".
"When you will go out to war on your enemies" - this is the battle with the Yetzer Hara
"and you will see horses and chariots, a multitude" - this is all the klipot (impure husks) that surround a man because of his sins. (Note: this includes the chemical pathways that have become ingrained in a person's brain through his feeding the addiction for so long).
"greater from (than) you" - the words "from you" are used, to imply that all these klipot of impurity indeed come "from you", i.e. from a person's own sins. Still...
"do not fear them for Hashem your G-d is with you, who took you out of the land of Mitzrayim" - just like in Egypt we were surrounded by the impure klipot and Hashem took us out of there.
"And when you will come close to the battle", explains the Beis Ahron, "and when you will come close to Hashem because of the battle, for this is the main (Ikkar) closeness to Hashem".
These are subtle but powerful words. It didn't strike me at first what he was saying, but then I read it again and it hit me. The Beis Ahron is saying that the main closeness to Hashem (the Ikkar Hiskarvus to Hashem) is though the battle with the Yetzer Hara. That means, even more than davening and learning Torah!!
This is very profound, and ties beautifully in with what we have said in the past that the most important thing to Hashem is not our progress in destroying the Yetzer Hara, but rather our dependency on him, and our constant knowledge that we need Hashem every day anew to help us break free.
Elya K wrote recently on the forum to someone: "I will tell you from 8 years of experience in Goyish 12 step groups, that I discuss more about G-d and fixing my character traits with these people than with any of my friends in Shul. Everyone in my circles is so focused on Halacha, but no one really talks about if we really give our lives and trust over to Hashem in our everyday life or not."
Do we hear what Elya is saying? It is specifically us, those who are struggling with the Yetzer Hara so intensely and are in a daily battle, that have the biggest potential for real closeness with Hashem! Like Elya said, even the non-Jews in the 12 step groups achieve a closeness to Hashem through their battle with the Yetzer Hara that unfortunately not even frum Jews always achieve! So imagine what potential for Kirvas Elokim (closeness to Hashem) a religious Jew has, who has both this struggle and the truth of the Torah!
