This statement is wrong. In my conversation with you I’ve said clearly a number of times that ego, I, self are the same thing. And this is evident just from the meaning of those words, ego means “I” in Latin, self accoding to dictionary means: “a person or thing referred to apart from others” so it’s me again, or you, or them. The problem with self arises because this word has been used in most indian spiritualities to mean a different entity, a higher one, from the ego. They say you can discover your “true self” and so abandon the ego. That is clearly a fallacy. They substitute an entity with another but all entities are illusory. Ego (we) is built through the process of identification and so it’s an identity. The self is just another identity so it has the same nature of the ego.
