How does sound interact with the physical and the ether?

[sjel]

I've been wondering about this for a minute.

I've read that the etheric template bodies are controlled by sound, but in a different sense than we experience sound in third density.

What does sound actually do on an occult level? My best guess is that sound waves travel through a medium, and influence the subtle vibrations of the material, connecting it to lie vibrations in hyperspace.

Alternatively, my second guess is that our brainwaves are what causes the change in hyperspace, and sound attunes parts of our brains to the right way of being.

Also, is everything on the higher levels of existence directly connected, or is there some medium of connection that is necessary (scalar waves, etc.)?

Or do things like scalar waves have an existence, but the unity is something separate (you know what I mean)?

Doesn't Hinduism and other ancient religions say that the universe is really just One Cosmic Vibration? and "Om," is the single vibration that is All. I think everything that exists in this Creation comes from Sound.
