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 WilberHuman beings are born and begin their evolution through the great spiral of consciousness, moving from archaic to magic to mythic to rational to perhaps integral, and from there perhaps into genuinely transpersonal domains. But for every person that moves into integral or higher, dozens are born into the archaic.
Ken WilberThat all oppositesโsuch as mass and energy, subject and object, life and deathโare so much each other that they are perfectly inseparable, still strikes most of us as hard to believe. But this is only because we accept as real the boundary line between the opposites. It is, recall, the boundaries themselves which create the seeming existence of separate opposites. To put it plainly, to say that "ultimate reality is a unity of opposites" is actually to say that in ultimate reality there are no boundaries. Anywhere.
