Okay... their definition of "meditation" is whacked.

And do to that, their results seem to be just as whacked.

i would describe meditation as a tool, the tool, to work with your mind.
And once you are actually working with your mind you can change things.
And stopping pain is a change.

But we really need to see which categories of pain we are talking about.
However allopathic medicine doesn't even believe in the categories that are used to define it... so... blah.

In the end, all pain can be cured with meditation.
But really, meditation is just the first step.
