Ego Death
It is clear here that the ego or self which is annihilated in
ego death is not the ego of depth psychology and it is not the
actual self. It is specifically the self-identity. The death of
this identity merely means that there is no barrier or resistance
to the Presence of Essence. (The Point of Existence, pg 524)

Ego death and reality
To be completely you means being alone. When this is experienced,
it will bring very deep grief and sadness. You have to learn to
say good-bye to everything you have loved -- not just your Mommy
and Daddy, your boyfriend and your cat, but to your feelings,
your mind, your ideas. You are in love with all of these. Letting
go of them will feel like a great loss, even a death. It is not
you who dies. What dies is everyone else. In the experience of
ego death, you don't feel you're dying; you feel everybody else
is dead. You feel you're all alone, totally alone. You have lost
a boundary which was constructed from past experiences. But this
boundary never really existed! It was just a belief. When you
experience reality as it is, there is no sense of boundaries or
of being separate, of inside or outside. (Diamond Heart Book 2,
pg 169)

Ego death and unity
Experiencing this unity reveals to us that life is beautiful.
Prior to this, when you experience yourself moving from the state
of the physical or of the personality to the state of the essential
or of the boundless dimensions, there is the feeling that life
is a problem. The best option seems to be to get away from life,
and one may long to disappear or die. From the perspective of
unity, there is no such thing as dying, nor of being reborn. There
is no such thing as ego death, and no such thing as enlightenment
either, since you are already the unity. This is the state of
affairs all the time and always -- before you develop an ego,
when it is dissolving, and after you are dissolved. All those
parts are the unity itself, and so you are not going anywhere.
(Facets of Unity, pg 88)

Death, ego death a misnomer
One important thing we see here is that there is no ego separate
from the soul. The proverbial ego of spiritual terminology is
nothing but the ego-self, the soul structured through ego development.
There is no ego as an entity; there is only the soul that can
become ego by becoming structured with mental forms. Therefore,
the idea of ego death is a misnomer. There is no entity that
dies, for the soul does not die. All that happens in such experiences
is that an ego structure dissolves, and the soul field is liberated
from its influence. More accurately, the soul ceases to structure
her experience through these mental forms. This can bring about
the dissolution or transcendence of one's identity, but this
identity is a feeling that arises from the soul being structured
by a particular self-representation. A representation dies, but
no entity.
Depth psychology itself, as in psychoanalytic theory, does not
recognize an ego that is an entity. Ego in psychoanalytic thought
is nothing but a mental structure, or a system of mental structures,
and the processes and capacities that go into its development
and functioning. In fact, some theoreticians consider the ego
to be nothing but the organizing process itself. "The basic
proposition we wish to develop is that the concept of ego, as
it has evolved through its several definitions in the course
of psychoanalytic theory construction, has become synonymous
with organizing process." (Blanck and Blanck, Ego Psychology
II, p. 15) (The Inner Journey Home, p 627, note 9)

Death, ego death
Beyond this experience, all light disappears, all awareness
ceases. There is no perception of anything; there is simply no
experience. When the soul is completely concentrated on the absolute
there is nothing to perceive, for to perceive total darkness
is not to perceive. Light is the awareness that arises out of
this total darkness, revealing that the absolute is prior to
light, awareness, and consciousness. This experience of cessation
is the experience of complete ego death, for it is going beyond
the world of manifestation, beyond even awareness of the world
of manifestation. There is no awareness of self or soul, for
there is no awareness at all, without this being unconsciousness
or sleep. When awareness looks out again, which we experience
as the return of awareness, the manifest universe reappears.
With the return of awareness the logos appears as the displaying
of time and space, and all the phenomena of the universe. We
are here the absolute, the luminous night, witnessing appearance
arising within it, out of it, but we still experience ourselves
as the immense stillness and stupendous silence underlying all
existence and all appearance. We feel fresh and clear, as if
our consciousness has dipped into the cleansing energies of the
source, and returned renewed and rejuvenated. This is similar
to the rejuvenation we experience after deep sleep, except we
are here clear and awake, bright and lucid. (The Inner Journey
Home, p 382)
These issues tend to arise naturally in life, especially during
transitions and intense events, but they also are brought forth
intensely due to the inner work. They arise especially as the
soul learns to penetrate and transcend her ego structure. To
follow our example, when the soul begins to see the limitation
of structure and experiences herself as presence, the structure
begins to reveal its nature as a mental construct characterized
by past conditioning, ideas, memories, etc. The soul begins to
experience an inner emptiness, a meaninglessness, a dread of
falling apart, and terror of death and annihilation. These experiences
of falling apart or being annihilated actually come to pass as
the structures dissolve. The soul experiences disintegration
and dissolution, disorientation, and a loss of identity; she
feels lost and despondent. These existential crises are actually
elements of some stages of working through ego structures that
then lead to deeper realizations of true nature, moving to timelessness
and formlessness. (The Inner Journey Home, p 231)
The capacity for global disidentification allows us to be permanently
in touch with our essential presence, although the identity and
the self-representation remains in experience. This condition
allows the experience of self-realization to arise, at least
occasionally, when the identity relaxes to the extent of total
absorption by (or into) essential presence. The more this capacity
for global disidentification develops, the more frequent, and
the deeper, are the experiences of self-realization. This development
continues, in principle, until permanent, full self-realization,
where total global disidentification coincides with complete
absorption of the self-representation, and complete openness
and flexibility of identity.
Complete flexibility of identity raises the phenomenon of disidentification
to a new level, beyond the normal egoic experience. This flexibility
involves the dissolution of self-identity, or more accurately,
the cessation of the activity of identifying. This condition,
which occurs in isolated experiences of self-realization, but
is the permanent condition of full self-realization (enlightenment),
is what is referred to by some traditions as "ego death" or "the
death of the self." In this state of complete annihilation
of identity, one does not have identity in the usual sense; our
identity is now with the presence of Being. In other words, our
identity has shifted from the self-representation to Being. (The
Point of Existence, p 129)
