Crystal healing: nonsense? This doesn't fit my experience

There was a big flap a while back on Google searches for "crystal healing" having spiked ... and how that was such nonsense.

Let me tell you about an experience I had in the 1980's ...

I was a young kid from the South who had moved to Seattle and met a Sophisticated Older Woman who recommended I try massage. I had never heard of such a thing, but this woman had recommended various other activities that were generally fulfilling, so I decided to try it.

I can't find an image of the kind of massage I received ... there are a lot like this, but mine was different.

The therapist started working on my back and shoulders, where I carry most of the tension, and came across a knotted muscle. She stopped and instead of working on it with her hands, took some kind of crystal (I think quartz), somehow focussed her consciousness through it, and the knot in my shoulder dissolved.

I have no explanation for this and no theory of how it could work. The therapist moved away maybe a year after I started seeing her, and I haven't found anyone else doing this since.

But don't be so sure that crystals are "nonsense" ... I'd love to talk with anyone who's had an experience like this or can refer such a practitioner!
