Mindfulness is first of all the ability to recognize what is happening in the present moment. It is a simple recognition – without judgment or criticism, without suppression or attachment. I breathe in and I am aware that the in-breath is here. I breathe out, and I am aware that the outbreath is here. There is no criticism or struggle. There is no effort to reject anything or grab on to it.
