"Paying attention, on purpose, in the present moment, non-judgmentally"
When you pay attention, you do so with intention to whatever is in front of
you in this moment, and when you see what is there you allow it to be as
it is. That is not to say that when you
allow something to be as it is, that you think it's ok. That's not
the point. Whatever it is may not be OK in your mind, but to not accept
something that is just because you don't like it doesn't mean that it ceases to
exist. To accept the present moment and whatever is there, as it is, gives you
the opportunity to choose your response to it. When you push it
away, ignore it, or deny its existence that increases your suffering.
For example, you step on the bathroom scale and it says you weigh 200
pounds. If you deny this fact you may continue to buy new clothes, eat
too much sugar, and insist that you're "too busy" to exercise. On the
other hand, if you step on the scale and it registers 200 pounds and your goal
weight is 180, and you accept that in order to reach your goal weight you need
to loose 20 pounds, then you can start to make the choices that will enable you
to reach that goal.
