The idea that somehow "no self, no problem"- I don't exist because I don't have a self- would be a mistaken understanding. However, the selflessness teaching is not that hard to understand. What it means is a type of self that people feel they have, like a fixed, unchanging identity. Either they know they have it, or for some, they feel they need to seek it, and possibly have an experience where they feel like they found something. That type of fixed, unchanging, essential self, or absolute self doesn't exist. That's what "no self" means. - Robert Thurman
