Put bluntly, the ego is not an obstruction to Spirit, but a radiant manifestation of Spirit. All Forms are not other than Emptiness, including the form of the ego. It is not necessary to get rid of the ego, but simply to live with it a certain exuberance.
Ken WilberSpirit forgets that it's Spirit and condenses to a smaller version of itself, which is soul. Soul forgets that it's soul and condenses to mind. Mind forgets that it's mind and condenses to body. Body forgets that it's body and condenses to the lowest dimension that you can have, which is matter.
Ken WilberFor what we don't realize today is just what the typical self of every previous stage failed likewise to comprehend: this is not the highest and greatest mode of consciousness which can be attained - there lie ahead the realms of the superconscious and the pitiful ego, by comparison, is as a speck of nothingness.
Ken WilberAs Hubert Benoit said, it is not the identification with the ego that is the problem, but the exclusive nature of the identification. When our self-identity expands beyond the ego, into the deeper psychic, then even into the Unborn and One Taste, the ego is simply taken up and subsumed in a grander identity. But the ego itself remains as the functional self in the gross realm, and it might even appropriately be intensified and made more powerful, simply because it is now plugged into the entire Kosmos.
