In the practice of shi-nè—remaining uninvolved—if thoughts come and go, simply allow them to lap like the tide. If you get caught up in a thought-story and lose the presence of your awareness in the movement of breath – just return to it as soon as you become aware of having drifted off. There is no need to get angry or irritated with yourself – these reactions are just opportunities to indulge in referentiality. Maintain an open, humorous and relaxed attitude. Expect nothing. Be attached to nothing. Reject nothing. Just be in the present moment.
