"Mindfulness is often likened to a mirror; it simply reflects what is there. It is not a process of thinking; it is preconceptual, before thought. One can be mindful of thought. There is all the difference in the world between thinking and knowing that thought is happening.
Mindfulness has no goal other than the seeing itself.
It is a form of participation - you are fully living out your life, but you are awake in the midst of it.
Thinking often comes between us and our experience. Inasmuch as it does, we are not intimate with that moment. We are not mindful."
