I once read an article about an American veteran who was in the Afghanistan war, fighting against Al Qaeda. The article said that, unfortunately, this soldier lost his foot. After the whole story of what happened, how he lost his foot in the war, he mentioned that he got a fake foot, one of those fake metal feet implanted into him. They asked him, “Obviously, insurance doesn't pay for that. How much did it cost you?” The guy said, “Oh, don't worry.” The soldier said, “It's cheap. It was nada.” How much was it? A half a million dollars, five hundred thousand dollars.
I thought to myself when I read the article: How can a guy say five hundred thousand dollars is cheap? That's a lot of money. You're talking about a half a million dollars. The answer is, Rabotai (my masters), when you're getting a foot, when you're able to walk again, five hundred thousand dollars—a half a million dollars—is nothing. If you know the value of what you're getting for paying five hundred thousand dollars, which is being able to walk around, then it's nothing.
The test of being Kadosh or being holy in our generation is not an easy task. It is a very difficult task. But if we will be aware of what you're getting, of how many blessings a person will get if he's actually Kadosh and watches his eyes, then the test of actually watching your eyes becomes much easier. They tell us that when a person watches his eyes, that Kedusha, that holiness, that Beracha, that blessing is actually passed on to his children. The Satmar Rebbe writes in his sefarim (books): If a father is careful about watching his eyes, his children will be able to see. His children will grow to be talmidei chachamim (Torah scholars). The Pele Yoetz brings down a father who's careful with Kedusha; his sons are going to be zocheh (to merit) to write chiddushei Torah, their own commentaries on the Torah. When a father is careful with Shemirat Einayim (watching his eyes), it's not only for your life; it's also for the sake of your children. The sefer Shevet Mussar brings down that a person who's careful about watching his eyes. Don't think that if, Chas Veshalom (God forbid), you're going to fall, it's only about your life. Also think about your children's life. The sefer Shevet Mussar. So every single time a person has the test of controlling their eyes, have your children in mind. When you are actually Kadosh, when you are holy, that Beracha, that Kedusha, that holiness is being passed down to the children. When you know how much you're getting for controlling your eyes, when you know the value—what happens when you're Kadosh—the nisayon, the test of watching your eyes, becomes much easier.
