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 Wilber..I sought a world philosophy-or an integral philosophy-that would believably weave together the many pluralistic contexts of science, morals, aesthetics, Eastern as well as Western philosophy, and the world's great wisdom traditions. Not on the level of details-that is finitely impossible; but on the level of orienting generalizations: a way to suggest that the world really is one, undivided, whole, and related to itself in every way: a holistic philosophy for a holistic Kosmos, a plausible Theory of Everything.
Ken WilberAll the things and events we usually consider as irreconcilable, such as cause and effect, past and future, subject and object, are actually just like the crest and trough of a single wave, a single vibration. For a wave, although itself a single event, only expresses itself through the opposites of crest and trough, high point and low point. For that very reason, the reality is not found in the crest nor the trough alone, but in their unity.
