We're coming back to the halachot of Shabbat,0:06and we're talking about the concept of psik reisha, where we said,0:11psik reisha basically is building up on what we have learned already.0:16So, hearing this for the first time, go back to the audio from last week.0:21But psik reisha, we said, is basically when a person is doing something that's0:27mutar, but the action that he's doing will certainly cause something asur to happen.0:32This is known as0:35psik reisha. This, the Gemara says, and that's a halacha that everybody agrees that it's still asur.0:39What the issur is, the right or the Rabbanan,0:41there's machloket rishonim. We won't get into that right now. There's something that's very, very similar to0:47psik reisha, and it's a machloket in the Gemara. We'll tell you what the psak halacha is,0:50where a person is doing something, an action that is0:54mutar, and the action may cause an issur, it may not cause an0:59issur. In that case, if the person's intention is not for the issur at all,1:04he couldn't care less about the1:06issur, but it's possible that maybe the issur might happen,1:10this is called in halacha1:15davar she'eino mitkaven. Davar she'eino mitkaven means something that a person is not intending for,1:18and davar she'eino mitkaven is different in psik reisha in one small difference.1:23Psik reisha, for sure it's going to happen.1:25Davar she'eino mitkaven means it might happen, might not happen.1:29Even the odds of it happening are very high,1:32but there's a possibility that it's not going to happen.1:34There's a real possibility,1:36not like, you know, of course, you know, if an alien comes from Mars and he shoots missiles.1:39We're not talking about that.1:40We're talking about something that it's possible it's going to happen, it could not happen.1:43Let's give you an example of walking on grass,1:46okay?1:47Pulling out grass. Let's start with the simple.1:49Pulling out grass is the next melacha that we're going to learn, which is called kotzer.1:52You're not allowed to rip out grass from the ground,1:54okay.1:55Now, what about if a person is walking on grass?1:58So, if the grass is high and you're walking barefoot, you can be assured that as you're walking,2:03grass will get stuck in between your toes and it will rip out.2:07Now, what are you doing?2:08You're doing an act that's mutar, which is walking,2:10a lot of walk on2:11Shabbat. But walking on grass barefoot, when the grass is a little bit tall, is for sure going to cause the grass to come out.2:18This is called a2:20psik reisha. And even though my intention is just to walk from here to there, will be a problem.2:24Now let's take a different scenario where a person is walking on grass, grass is not so tall,2:29or, and he's wearing slippers, shoes, something else, where it's possible that as you go,2:35something might get stuck and get pulled out.2:37It's very possible,2:39but maybe not.2:40Maybe yes, maybe not.2:41It's not 100%.2:42In that case, if your kavanah is not to rip out the grass, so you're allowed to walk,2:47but it might be, and sometimes you're walking and say, Ah, look something2:50here. But again, it's not for sure going to happen.2:53Since it's not for sure going to happen,2:55that would be called davar she'eino mitkaven and2:58v'mutar. Let's bring it to something a little bit more practical that people ask all the time.3:03Rabbi, I have this water cooler in the house.3:07You press the cooler things and the machine goes on,3:11it doesn't go on.3:11Can I use it on Shabbat, basically?3:13You know, we're talking about the, they call it the cold spring, whatever.3:16Basically where the person is filling up a cold cup of water on Shabbat,3:19he wants to know, can I use it or not?3:21Or she wants to know also,3:23women also like to use it.3:24Okay,3:25so what's the3:26halacha? Halacha, it depends how the machine operates.3:28If every time you take any amount of water from the cooler, the machine goes back on, right?3:35So what's your act?3:36Your act is taking water, right?3:39There's no problem to take water.3:40It's a regular lever,3:41you're just taking out water.3:42There's no problem3:43taking out. But when you're taking out water, it's causing the machine to go on, even though you couldn't care less for it,3:48right?3:49That would be a psik reisha and would be a problem,3:51because every single time any amount of water goes out, the machine goes on,3:55the electric goes on.3:56So even though that's not your intention, but it's happening, psik reisha, it's a problem.4:00However, if when you pull out water... Sometimes maybe it might go on,4:05doesn't go on.4:05It all depends on what it reads and what's going on inside.4:08It's not for sure going to happen every time.4:10So that's not called a4:12psik reisha. That would be called4:14davar she'eino mitkaven. If your kavanah is really not, you couldn't care less if it goes on now, later4:18on, you couldn't care less, right?4:19So that's called4:21davar she'eino mitkaven. Davar she'eino mitkaven would be okay,4:23and that's the rule.4:24Again, we're giving rules over here of these rules, and it could be applicable, you know, in all different areas.
