Mindfulness is not thinking about things. (It is not “meditating on” some topic, as people often say.) It is a non-discursive observation of our life in all its aspects. In those moments when thinking predominates, mindfulness is the clear and silent awareness that we are thinking. I found it helpful and relaxing when someone said, “For the purpose of meditation, nothing is particularly worth thinking about.” Thoughts can come and go as they wish, and the meditator does not need to become involved with them. We are not interested in engaging in the content of our thoughts; mindfulness of thinking is simply recognizing we are thinking.
