The point is that you free the ego. The ego is only a pronoun. It's a Greek first person pronoun, ergo. When you're in Greece you say, Ergo wants to take a bus, and you don't mean your ego wants to take a bus, like some big entity, you only mean I want to take a bus.
You have to be responsible for yourself, refer to yourself, develop yourself, help others, whatever it may be. So we shouldn't have an idea that the whole thing is to shatter ones ego.
You're more responsible ethically for being there with your interconnection to the world, but the you now is an always changing one, and you're responsible for how you change it. It's very important to understand that whole thing about the ego.
