By identifying with a particular name that belongs to a particular body and mind, the self begins the process of creating a separate identity. Add in a complex jumble of ideas, beliefs, and opinions, along with some selective and often painful memories with which to create a past to identify with, as well as the raw emotional energy to hold it all together, and before you know it, you've got a very convincing - though divided - self.
