We try to maintain a relaxed observing, and not identify with our thoughts. The heart of mindfulness practice:
To think ‘I am screwed up’, is a value judgement, isn’t it? ‘Screwed up’ makes the ‘I am’. It is identifying with a certain kind of condition, a feeling about oneself personally. If we leave off the ‘screwed up’ bit, we get more to the reality of the moment ― ‘Right now I am . . .’ and there is this sense of being here and now. This is a recognition of conscious experience as an entity. There is an entity but it is not personal any more; it is not ‘I am Ajahn Sumedho’ or ‘I am’ anything at all; it is just this sense of ‘I am’, of presence. Being a conscious entity is ― ‘like this’. Reflect on that and sustain it for a while, that sense of ‘I am’, without adding any personal conditions to it.
In this sense of ‘I am’, the body is ‘like this’. There is consciousness, there is the breath (one can be aware of just the breathing of the body, in-breathing and out-breathing.), there is the ‘sound of silence’, the background. And in this intuitive moment, one observes without adding any kind of personal quality.
