I just randomly found another whole depressing category of metaphysical eBay BS:
And yes, a Completed Items search confirms that the dealers do quite often actually sell their "Professional 11 Planetary Tuning Forks for Prosperity", "Tuning Fork set Chiropractic Physical Therapy CHAKRA", "Heal-HUMAN Intestine-INTESTINAL ORGAN TUNER Tuning Fork" and so on. And, also as usual, it's not just one nutty seller - though there is only one who's responsible for most of the current listings.
Apparently many of these forks are meant to have something to do with the "sacred Solfeggio scale", which I am delighted to say my entertaining friends at Life Technology have a page about. "These previously secret sound frequencies are thought to be the tones of creation and destruction"!
(I don't know whether their Solfeggio CD works better than a set of tuning forks. You'd better get both, to be sure.)
Various other independent thinkers will also be pleased to tell you all about the Sacred Solfeggio Scale. Apparently, you're going to have a hard time "activating" all of those extra strands of DNA without the help of the Sacred Solfeggio!
Solfeggio, or Solfège, is actually just a name for perfectly ordinary do-re-mi scales. The frequencies of the six notes in the Sacred scale (I think six is all you get) don't seem to have any particular mathematical relationship, so the "Sacred" scale doesn't really seem to qualify as an actual temperament or scale. But, y'know, if it doesn't seem to make any sense, that's just more evidence for how transcendental it must be. So I suppose the Super Secret Sacred Solfeggio Scale is every bit as special as everything else that's supposedly sacred.
Tuning forks do actually actually do something without the assistance of the human imagination, which is more than can be said for magical crystals and haunted costume jewellery. But I still can't escape the feeling that I should start selling large ball bearings as haunted scrying globes, or something. There are idiots out there who're determined to spend their money on some sort of crap, after all - as I've said before, I, or almost anybody for that matter, is likely to be more deserving of that money than the people who usually get it.
