I see a lot of new-agey type of stuff about people
raising their frequency and vibration, but never tell you how to really do it, so it ends up in the realm of
quackery My cousins have read a book which they have highly recommended to me on many occassions (darn, now I forget the exact title) but I know its about sound, reverberations, vibrations, etc. and its all about the scientific research on those things and their effects on the human body and mind. So there is some sources out there that aren't necessarily 'quackery' (lol), if you are interested enough to search it out.

Keep in mind, that book really isn't Buddhist related at all I dont believe, but I figured it was on topic and could be a very interesting read.

Loosely, from my cousins explanation, I believe it discusses things like music and sound and their effects on our mind and body (and goes into experiments how plants exposed to rock and roll will die and plants exposed to classical music bloom and grow strongly, etc.), and those kinds of things. I believe there is also information in there about the "om mani padme hum" meditation and its vibrational effects.

If you are interesting in knowing the title, I can text my cousins and find out for you.
