It is possible to harness the natural mechanism of yawning to help discharge harmful energy associated with some topic, whether person(s), place(s), event(s) or more. Yawning is sometimes thought of as negative, in that we often yawn when we are bored or sleepy or don't understand something. But yawning is more usefully looked on as being positive, a means of releasing negative energies.
This is most clearly seen in a practical demonstration, rather than just analytically thinking about it. For this demonstration, you should be well-fed and well-rested, not under the influence of drugs or alcohol, and with maybe half an hour to spare. If not, it would be better to skip the whole thing for now. You should also be willing to address some area of your life that is troubling you, whether momentary like an argument with a loved one, or something more long-term. The idea is that this procedure will help you with whatever you are going to address in a moment, although it is fine to be skeptical about that. You will probably find it easier to get through this demonstration in a room by yourself where you don't have to worry about others looking at you.
Has anything sprung to mind that you would like some help with, whether or not you think it is possible to be helped in that area? If so, go with that topic and skip to the next paragraph. If not, here is an example that should work with most people: Have you ever had a loss? Maybe your mother died? Your girl ran off with someone you thought was your friend? Your boyfriend, who you still love madly, dumped you? Your best friend isn't talking to you, maybe forever? A loved one who isn't there any more? Have you experienced anything like that?
OK, let's say you are now feeling bad about something. Yawn! Make yourself yawn. Yawn, yawn, and yawn again. If you are feeling sleepy, then TOUCH STUFF! Right away! With your hands, touch the table firmly. Rub your hands together hard. Yawn. Rub your arms. Rub your legs. Rub your chest. Yawn. Squeeze the sides of the chair. Rub your feet on the carpet. Tap your fingernails on the table. Stamp your feet. Scratch your head. Even stretch. This kind of thing. Do whatever makes you yawn, right now. But touch stuff. Don't just think about it, but actually touch stuff! And yawn. Yawn, yawn, yawn. Yawn though your jaw maybe aches. When you can touch stuff without yawning for a full minute, by the clock, you can go on to the next step. But note that you no longer feel sleepy.
How does this work? It is as if a person needs a certain minimum amount of energy around them, even if there is bad energy mixed in with the good. If someone only has this baseline minimum, they will not be able to get rid of bad energy. Touching stuff, like rubbing the hands together or arms or legs or chest or whatever, energizes the person, i.e. the person sucks in more energy from the environment. This increases the total amount of energy the person has, and they can afford to let go some of the bad energy as they now have energy to spare. Continuing the process of rubbing (good energy in) and yawning (bad energy out) discharges more of the harmful energy connected to what one's attention is on. If one stops rubbing, i.e. stops building up one's total energy, the yawning will soon stop as one gets down to this minimum baseline energy level.
With regard to feeling sleepy, it is as if one has, say, one hundred units of analytical thinking power. If one is somewhat upset, say, maybe only fifty units of analytical thinking power remain, and the other fifty are temporarily tied up in a battle with the upset. If the upset is more pronounced, maybe only ten analytical units of thinking power remain for now. As the number approaches zero, one "goes to sleep", either with eyes closed or just staring into space.
The next part of the procedure is to take your topic (a mental idea of what you are dealing with, like the loss of your loved one or whatever), and put it out there. Mentally put it out there. Yawn. This should make you yawn more. Keep doing it. Put it in front of you, behind you, into the wall, into the supermarket, behind the moon, into next week, anywhere as long as it is out there. You want to produce yawns. It's OK if the topic changes a bit, or you are mainly thinking of only one aspect of it, but don't shift to something else completely until you have got all the yawns you can out of this one. After a few out-theres, touch stuff again. Yawn. If you're getting sleepy, touch stuff a lot. Remember, it is as if a yawn is a blow against sleep, but you have to keep recharging your batteries by touching stuff or you won't be able to yawn away the harmful energy.
It is OK if putting it out there doesn't make any sense. Maybe it just kind of sits there in your head, and maybe it doesn't make any sense to be think something "out there" anyway. Almost anyone can do this, even if it seems impossible at first. If your topic is too heavy, kind of mentally hold it still and back away from it a fraction, a tiny, tiny bit. You want to put some distance between it and you, but not by putting it out of your mind completely. If you can't manage the whole thing, put a small part of it out there. One can usually manage to put one molecule, or one electron of it out there.
Remember, you want to produce yawns. If you started with a topic that made you yawn, or something that makes you feel sleepy, touching stuff or putting it out there should produce a lot of yawns, "a lot" being ten or fifty or even more if it is a heavy topic.
One other useful technique that is part of this procedure is to "Tell it." It is often good to talk to the computer screen about the topic you are dealing with, or talk to the wall. Express emotion. Or write things down. Some people find it useful to have a record of the topic addressed, the time the session started and ended, how many yawns produced and on what, and the overall result. You may realize something important, and want to have a record of it. You can produce yawns doing this. If so, keep doing it. Do whatever is producing yawns, until it no longer makes you yawn. Don't write or say lots of stuff if it doesn't make you yawn as that is a waste of your time. This is The Yawn Machine and to get the benefits you need to be yawning.
