Bhante Henepola Gunaratana writes in his article “Mindfulness and Concentration” from the Fall 1998 issue of Tricycle,

In a state of mindfulness, you see yourself exactly as you are. You see your own selfish behavior. You see your own suffering. And you see how you create that suffering. You see how you hurt others. You pierce right through the layer of lies that you normally tell yourself, and you see what is really there. Mindfulness leads to wisdom.
