So now, for Bhastrika, you have to sit with your back straight. So if you're sitting on a chair, then you sit with the knees below the level of the seat. Let your knees fall below the level of the seat of your chair. Automatically your back becomes straight. If you're sitting in Vajrasana, this automatically happens. When your hip is above the level of your knee, your back becomes straight. See, now I explained Vajrasana also. Done. Okay.
So now, for Bastrika, we start with the palms in a loose fist. How loose is the fist? It is not like a boxing. It's a tight fist नहीं है। किसी को, you don't have to punch anybody. No. How loose is the fist? The tip of your fingers should gently touch the palm. You see, gently they have to touch the palm. This is how loose the fist is. And the thumb is on the outside. The thumb is on the outside. Not like this. Thumb is on the inside नहीं। Thumb is on the outside. Okay. And you start with the palms in front of your shoulders. Not like this. Not like that. In front of your shoulders, as close to your shoulders. And the elbows are touching the body. ऐसे नहीं। Not like this. Not like a chicken. ऐसे। नहीं तो। This is not Bastrika at all. Side of your body.
Touch. So elbows touch the ribcage. And then when you breathe in, I will just show you first. When you breathe in, you breathe in through the nose, normal breath. And as you breathe in, the arms go up and the palms open. So ऐसे। Straight up. And when the hands come down, the palms will close into the loose fist again. Like this. You see. And now, when the arms fall, so when you breathe in, it goes, palms open. And then on the out-breath, the palms, the arms will simply fall by gravity, you don't have to do anything; they will automatically fall by gravity and will hit the side of your chest, and then the breath will be expelled out from there like this. You see, it's effortless. You saw my face; it's not becoming like this. This is not Bhastrika; this is drama. There is no such thing. Bhastrika is very effortless. Okay, let's do it. Palms in a loose fist in front of the shoulders, elbows tucked in close to the body, neck relaxed, and face forward. Keep the eyes open so you can see me, and then you repeat. Okay, normal breath in, out, and begin. Up, down, up, down, stop. Stop. Got it? Effortlessly, the arms fall, and when it hits the side of your ribcage, the breath is expelled from your nose. That’s it. That’s Bhastrika. And you do it in moderate pace. You don't do it like an express train, no; you do it at a moderate pace like this. All right, and then you sit.
If you have done the Advanced Meditation Program, then you apply the locks. All right, you do this for between 15 and 20 times up and down, then you rest. 15-20 times up and down, then you rest. 15 to 20 times up and down, then you rest. And then you do the next thing, which is om. All right, very simple, effortless. Have you seen Guruji doing Bhastrika? It is so effortless. Most people don't do Bhastrika effortlessly. And why do we do Bhastrika? Bhastrika is done because, in the subtle body, even though you're breathing normally, there are pockets of prana that are not moving, you know?
So, like if you have a network, how many of you have, how many of you have now cooking gas coming to your house in a pipe, no longer cylinder? It's pipe, right? Okay, so that whole pipe network is full of natural gas, which is methane. But when that pipe is opened, when the network of pipes is open for any maintenance purposes, then air goes into it. So there are pockets of that pipe that even if you keep flowing the natural gas, that air will never get dislodged from it because it's in a pocket, it's in a dead zone. So the way they dislodge the air is they pressurize and rapidly depressurize the entire system. So they pressurize, pressurize, pressurize, like this, they do it like five times, and then those pockets get dislodged.
The same thing is happening in Bhastrika. You breathe in, and this rapid exhalation on the level of the physical body is dislodging the stuck prana, which is on the level of the subtle body. That's what's happening in Bhastrika. Also, when you do the bandhas, when you do the locks, what is happening is in the physical body, the alveoli structure in the lung sometimes gets kinked. Not sometimes, it usually gets kinked because those alveoli bend, and then the pipe kinks, and then it's not functional. It becomes dead volume.
So, in science, in medical terms, they say it's the lost capacity of the lung. Okay, so when you do the bandhas, what's happening is you're taking the breath in, and you're holding it, and you're locking all the three locks, and that pressure unkinks it. So let's say that pipe is kinked like this; that pressure that's coming from the lung will unkink that pipe, and then that alveoli becomes active. Which is why the Bhastrika, which is why the bandhas are done after Bhastrika. Then the net usable volume of the lung becomes higher, and while you're doing the bandhas, the prana in the subtle body is getting assimilated. That's what's happening in the subtle body, or in the physical body, the unkinking of the network of pipes leading to the alveoli is happening. So the working volume of the lung goes up, so that's why we do Bhastrika.
And there are other benefits also about the brain going to a gamma wave state, but don't worry about all that. These are the two things that are essential.
