numerology = pseudoscience (aka total crap)

What is "a vibrational frequency of balance" supposed to mean?
Can anyone explain it?

"the vibrational frequency of the prime number doubles in power"
Frequency has nothing to do with "power" or "energy".

You can certainly double a frequency (make something vibrate twice as fast) as any TV engineer will confirm. And you can make a vibration more powerful. But you can't double the power of a "frequency".

And if you don't mean the mathematical concept of frequency, then you should call it something different to avoid confusion.

I doubt that the author of that phrase has ever heard of simple harmonic motion (a genuine mathematical description).

"It represents male and female equality".
Glad something does...

Believe it all if you like, (plenty of people believe in all kinds of nonsense anyway, like astrology, scientology, even alchemy, I suppose) but there is nothing rational, logical or sensible behind it.
