Yoga has taught me a lot about visualization of intentions and about freeing myself of thoughts.
One thing I am working on a LOT now is an AA concept and like Scott, I'd venture to say one of the overall good life aims I have. It came to me one day in yoga when I could not get thoughts of my step daughter or worse, my husband's ex wife out of my head.
Kickball.
You easily plop off a person's pretty little head and it goes in a clear version of a kickball, with just that rubber band around it. You kick it way into the distance, and they go out of your head in that ball. There's an anti-rebound feature that prevents returning most of the time - but if the ball does bounce back, the head has remained undamaged and can be reattached to that person as you let them go on their merry way. I mean, I'm not a monster, I just don't want the wrong folks getting my mental energy or impacting my emotional balance.
And it makes me giggle to visualize it.
