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 WilberThe very desire to seek spiritual enlightenment is in fact nothing but the grasping tendency of the ego itself, and thus the very search for enlightenment prevents it. The 'perfect practice' is therefore not to search for enlightenment but to inquire into the motive for seeking itself. You obviously seek in order to avoid the present, and yet the present alone holds the answer: to seek forever is to miss the point forever. You always already are enlightened Spirit, and therefore to seek Spirit is simply to deny Spirit.
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 WilberEarly morning, the orange sun is slowly rising, shining forth in empty luminous clarity. The mind and the sky are one, the sun is rising in the vast space of primordial awareness, and there is just this. Yasutani Roshi once said, speaking of satori, that it was the most precious realization in the world, because all the great philosophers had tried to understand ultimate reality but had failed to do so, yet with satori or awakening all of your deepest questions are finally answered: it's just this.
Ken WilberSo it is a good idea to start simple, I think, and be very careful. There is a spiritual opening in the Kosmos. Let us be careful of how we fill it. The simplest is: Spirit or Emptiness is unqualifiable, but it is not inert and unyielding, for it gives rise to manifestation itself: new forms emerge, and that creativity is ultimate. Emptiness, creativity, holons.
