create a gap in the mind stream simply by directing the focus of your attention into the Now. Just become intensely conscious of the present moment. This is a deeply satisfying thing to do. In this way, you draw consciousness away from mind activity and create a gap of no-mind in which you are highly alert and aware but not thinking. This is the essence of meditation.
