As 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.
Ken WilberIf Spirit has any meaning, it must be omnipresent, or all-pervading and all-encompassing. There can't be a place where Spirit is not, or it wouldn't be infinite. Therefore, Spirit has to be completely present, right here, right now, in your own awareness. That is, your own present awareness, precisely as it is, without changing it or altering it in any way, is perfectly and completely permeated by Spirit.
Ken WilberTo understand the whole it is necessary to understand the parts. To understand the parts, it is necessary to understand the whole. Such is the circle of understanding.
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.
