theres a device from tesla, the earthquake machine, its the size of an alarm clock or so they say, and he put it on a buildings frame or something, and adjusted the frequency til it matched resonance with the metal, then it would tap the metal or something, then the house would eventually sway and collapse. It works like how a pendulum does, or like how moving on a swing does with someone pushing you intervally, if they push you at the right frequency then your speed will increase and increase. The momentum of the house wasnt visible at first, but the constant prods from the device caused it to sway and nearly fall over. The workers there thought there was an earthquake so tesla removed it and took off lol. They say ti can destroy the brookelyn bridge in under an hour, it weighs about 3 pounds.
imagine if a human resonated with the bridge in such a way, he weighs much more than three pounds. He coudl collapse the bridge even (though sadly himself as well lol, the bridge support he would have to be on.)
So how i see it is, pendulums are related to frequency, like when you push a person on a swing at the same interval causing him to speed up, pendulums work this way, the device is similar to a pendulum because it hits it at the right frequency, or interval, til it gets destroyed. So telekinesis should be like, spinning the pendulum in a circle having it gain momentum and gain momentum, until you release it so it hits an object at its center of gravity to knock it back. For example, if you want to slide a box it needs to hit perpendicularly to the boxes gravitational pull, to its center of gravity, so it needs to hit full forcedly there. But question now is, how can telekinesis be done? It would have the force needing to move through the air or ground or electrically is how i see it, but im not decided on this yet.
For astral projection, breathing makes a difference. Breathing is intervally just like frequency, and breathing can help to induce different kinds of mental states. Because of this it could be alikened to resonance. Also because people speak of vibrations, like a very fast frequency. The destruction of the house would have to be around the gravitational center of the house where the force is applied, or so ive been told. I think telekinesis would be applied to the surface of an object, like to slide something or roll a ball or somethign without touching it. Astral projection could be a surface area resonance, or it could be a changing of frequency to a specific zone in the body and mind. Its something to do with this i believe.
Humans have brainwaves anyways and a yogi i spoke to said the way you breath can be a key to unlocking different mental states or abilities he thinks. I know the way you breath, conciously or subconciously, is from the amygdala, which also affects heart rate, metabolism and other things. So it could very well change your brainwaves from how you breath.
Also something else thats interesting will be at the bottom of the links here. Dowsing.
