Point number one is right after you say it. What exactly is that? It's a word in Aramaic. Now, this is called bitul because, in order for you not to be over on bal, you can't have any Chametz (leavened food). What happens if, by mistake, on Pesach you find a piece of Chametz in your house? Okay, but the pasuk (verse) says you're not allowed to have any Chametz in your house. So is this considered like you have Chametz in your house? And the answer is, before Pesach it doesn't belong to me. I made it worthless. So you have to say these words. What do these words mean? You know them by heart. What does that mean?
Dela chazitei udela bi'artei, libatel velehevei hefker (belonging to anybody who wishes it) ke'afra de'ara—that which I didn't see and that which I didn't get rid of should be, should be like the dust of the earth.
So now, what if you go away for your second days and can only see your destination after the fact, after Pesach was over? Then you went to another place, then you saw Chametz. Where's this other place? For example, a hotel. A hotel. So a hotel is a hotel. That's number one. Then you have, for example, a house that you own in a different state. Let's say, for example, you're going to Israel on Chol HaMoed (intermediate days of the festival), so you have to make sure that that house is already taken care of before Pesach. Don't wait until Pesach. Send a messenger, someone you know in Israel. You should set it up in advance, give them access to the place, and make sure that if you're going for Pesach, it's cleaned by the time you get there. If you happen to get there when it's not cleaned, obviously you have to do the bedikah (search) when you get there. Make sure you get rid of everything as soon as possible. Same thing as with a hotel. Come to a hotel on Pesach.
So anyways, when it comes to a hotel, everything is basically clean. The only thing is, sometimes they have on the side maybe, like, cookies. Yeah, let's say cookies; they might have something like that. So obviously, the second you come to the room, do your bedikah, and if you find any during Chol HaMoed, dispose of it right away. So that's number one. Number one is, after you finish the bedikah at night, you do bitul, bitul, bitul, and make sure you understand what you're saying. If it's in Aramaic and you don't understand Aramaic, make sure you have a type of interpretation. You have to understand that when you say it, you have two things in mind: it's both Chametz and Se'or. What's the difference between Chametz and Se'or? Chametz is the actual Chametz. Se'or is something that's called sourdough. It's the Chametz that became so Chametz that it even makes something else Chametz.
What's bitul? What am I doing right now? I'm making it hefker. It doesn't belong to me anymore. And it doesn't belong to me now. The truth is, how come you have to do a bedikah? Just do bitul and that's it. So why did the Chachamim (sages) make us do bedikah? Why don't I keep my Chametz in my closet and say all the Chametz that I have is worthless, it's ownerless, doesn't belong to me? That's enough, no?
Two reasons. Reason number one is, what happens if on Pesach you find a nice, beautiful Danish muffin on the side over there that you left in your closet, and you come on Pesach and you're going to come and eat it? Don't keep it in your property. As long as it's in your property, you might come to eat it. That's number one. Number two, let's say you have a whole cabinet of beer or whiskey—a cabinet of whiskey, Blue Label. Is that Chametz? Blue Label in your, and you say, “A whole Blue Label is worthless, it's ownerless, it doesn't belong to me.” Anybody? I mean, you don't really want to give it up. You're saying words, but you don't really mean it in your heart, and bitul has to be ba'lev (in the heart). What do you do? One of two options: either get rid of it or sell it. So when you sell it, even though you really want it, but I sold it, so it doesn't belong to me. After Pesach I know I'm going to get it back and everything will come. In your heart it's come. The point is that you can't just say it doesn't belong to me because in your heart you really want it to belong to you. Therefore, you have to make sure that you either get rid of it or sell it.
Let's say you have pitot (pitas) in the freezer; you have to throw it out on the floor. Same thing, that's Chametz gamur (complete Chametz). Get rid of it, meaning eat it before Pesach. Don't buy an extra amount a few weeks in advance when you're ready to start preparing. What happens if you have leftovers? Either way, you have leftovers; you have two options. Again, you get rid of it somehow or, worse comes to worst, you sell it, even though it's not the best thing to do. We don't like to be in this situation.
If you burn it during bi'ur chametz (burning of Chametz), it depends how much you have. You have a pack of five pitot, a pack of five pitot. You're not going to eat it before Pesach, you're not going to eat it before Pesach, so you can be mekayem (fulfill) a mitzvah (commandment) at bi'ur chametz. It's a mitzvah. If it's inyan hefsed mamon, you have a big loss, so then keep it. If it's one box, for example. Yes, say the bitul three times. When you say this sentence three times, it's the Hida. It says to repeat it three times. Why three times? Because when you say something three times, it's like a chazakah, it's real. Even if you say it one time, you say it three times.
