The book to the right is one of many good books to read regarding the research of Human Psychic Abilities. During the 1840's to 1940's, there was some serious psychic research going on, hundreds of books were published, but then right after WW2 the whole subject seems to have gone underground.
Sound is a vibration and a good example of Psychic Forces at a lower frequency that we can all see, feel & hear. I found one WEB SITE with an interesting video that helps explain some complexities of sound.

If you can visualize higher frequencies in a three dimensional world, acting on the particles in your body from above, below, to the right & left, front & back, etc., all around you ...and contemplate how they could "form" a structure such as your finger, arm, etc. with vibrating the billions of cells & particles that make up your body, then, you may gain a slight understanding of how thoughts can control matter, after all,.... thoughts are vibrations.
A good example, is our own Solar System, the Sun, Earth, the Moon, & all the planets. It's vibrational like activity that keep all these heavenly body's in their orbits. On a larger scale, is our Milky Way Galaxy, these same forces keep the star systems in the shape they are in, which looks like a hurricane , eye and all. Whether it's the Sand & the Sound Vibrations in the video on the left, or on a larger scale, the Sun & the Planets, or even larger, the hugh yellow ball at the center of our Galaxy & the millions of suns revolving around it, invisible vibrational forces control all matter.
