If you can see a thought you have the opportunity to realize that you are not that thought but separate from it.

It's like going into a candy store. You see the candy and your mouth starts to water you can already imagine how it's going to taste and you want it....but when you instead of eating it change the focus of your attention let's say onto a Horror show.....where did your desire for sweets go?

It is the focus of attention that gives power to creating your experience.
