As you continue to practice mindfulness and awareness, the seeming confusion and chaos in your mind begin to seem absurd. You see that your thoughts have no real birthplace; they just pop up. You see that your thoughts don’t go anywhere; they are unceasing. You also see that no activities are really happening in your mind. So the notion that your mind can dwell on anything begins to seem absurd, because there is nothing to dwell on.
The point of meditation practice is not to make your mind a blank. Instead, as a result of super-mindfulness and super-awareness, you begin to see that nothing is actually happening–although at the same time, you think that lots of things are happening. Therefore, realizing that the confusion and the chaos in your mind have no origin, no cessation, and nowhere to dwell is the best protection.
