What is the concept of "Ego" or "self "? What is the concept of "Ego" or "self "?
In buddhism there's concept called no self.Does is mean there's no "me" at all or does it mean that "me" cannot understood with out " you ".
The Buddhist concept is not no self but non self or not self. What this means is there nothing that can be taken as self. There is no permanent unchanging core or soul, there is nothing which you command and control absolutely, there is nothing that an external agency (e.g. God) commands and controls.

Identity view is considering your 5 Aggregates as self, i.e., you consider your body and / or mind as self. In which case if you consider after cutting your hair that this hair is me or a part of me on the floor. The toilet pit is full of me because it was in me at some point. Likewise you should not consider past memories, experiences, thoughts or even your own body as me or mine, because there is no me or mine in the constituting parts, there is no control in any of the parts, each constituent is governed by its own universal law and process which you cannot control.
