(Spirit Rock Meditation Center) After clarifying further the fundamental practices of our retreat, particularly the three ways of seeing leading to liberating insight, we examine the third way of seeing—seeing anatta (or not-self). We focus less on understanding this way of seeing conceptually, and more on identifying two main ways of practicing—(1) opening to being mindful of the flow of experience, increasingly with a “thinned out” self or lack of self, and (2) noticing and being mindful of when there is a “thick” sense of self.
