A few years ago, well, in the late 1980's / early 1990's, BASF, the German chemical company (they stopped making cassette tapes years ago) ran an advertising campaign with the tag line -
We don't make a lot of the products you buy. We make a lot of the products you buy, better.
And so it is with Mindfulness. Mindfulness doesn't try to change or make anything different, or better; not the world, not us. It's far more radical than that.
The natural ingredient of Mindfulness is just about being. How to ... be, first. How to do "being-ness." as Kabat-Zinn says. In the world, anywhere.
Then, though nothing has changed, everything's different. For the better.
