This Dhamma dialogue reviews three levels of awareness related to mindfulness of breathing and how they interact with the practice of vipassana, that is, insight into the impermanent and selfless nature of personal experience.  The first level is simply being aware “This is the in-breath, this is the out-breath”.  The second level is a cultivated interest in the “textural” quality of the breath sensation, while the third level narrows the focuses the concentrated awareness around a discrete, singular sensation “like noticing the sensation of one nasal hair vibrating”.  How each level relates to the practice of vipassana was described and then there was a general discussion of these practices.
