After situating today’s theme in the context of the nature of the “ordinary habitual mind” and how it is transformed, we look at the fourth parameter of transformation: the nature and sense of self. We start by recognizing the often conceptually confusing nature of this area, and then proposing a primarily practical way to approach the area. We first identify the conditioned sense of self as permanent, independent, and separate, how this sense of self manifests in various ways and why this can be a problem, connected with suffering. , We then briefly suggest how the elements of such a conditioned sense of self are absent in an awakened being and how other positive qualities are present. Finally, while recognizing a number of complexities, including developmental issues, we look at two practical ways to explore and transform the conditioned sense of self: (1) by looking out for and being mindful of when there is a “thick” or “big” sense of self, and (2) finding various ways, in the flow of daily life as well as in formal meditation, to “thin” out the self, developing ways of experiencing with no or much less of a sense of self.
