Emptiness
At this point the person might go on to experience himself as
empty space, devoid of fullness or quality. If he deals with the
associations he has to this emptiness - such as those of dependency
and need - and the fears produced by them - probably the fears
of disintegration, disappearing and so on - then he will remember
the old hurt that cut off the Essence. This is another big dark
spot. The person will unearth the painful situation or situations
that ultimately led to the loss of this particular aspect of Essence.
Besides the memories and affects, the individual will experience
the emotional hurt as a wound. It will feel physically like a
wound in the chest, but it is a wound in the energy system that
corresponds to the emotional hurt and the loss of Essence. When
one allows oneself quietly to experience the hurtful wound and
the memories connected with it, the golden elixir will flow out
of it, healing it, and filling the emptiness with the beautiful
sweet fullness that will melt the heart, erase the mind, and bring
about the contentment that the individual has been thirsting for.
(Essence, pg 116)

Emptiness types
We see then that there are two experiences of emptiness: One
spacious and liberating and the other deficient and oppressive.
The subjective experience is definitely different and distinct
for each of these kinds of emptiness. (The Void, pg 118)

More accurately, we can say that the subjective experience of
space is felt as completely different from that of the experience
of deficient emptiness, although both experiences have in common
the sense of the voidness. (The Void, pg 119)

The holes we discuss are not only forms of emptiness, but the
emptiness feels specifically like a lack, accompanied with pain
about something missing. When we investigate such deficient emptiness,
what arises is normally not a longing towards something new, but
pain, a wound of loss. Sometimes the emptiness will appear with
a longing for what is missing, but when we investigate this longing
emptiness it will also lead to the same wound. This wound, instead
of reflecting a lack of new development, reveals, upon investigation,
a childhood history of loss. Both the emptiness and the pain reveal
one's personal history of how the particular aspect became disconnected
from one's experience. It is usually when such childhood content
is fully understood that the essential aspect emerges in consciousness.
(Inner Journey Home, pg 544)

Emptiness, spaciousness and fullness
As you let go of the ego structure, you see that its nature
is empty, since it is actually conceptual and not ultimately real.
This is when you feel the emptiness; the sense of emptiness is
really just the revelation of the structure's immateriality. As
you stay with the emptiness, it reveals itself as spaciousness.
Then the spaciousness brings out the fullness inherent in it,
which is all the holding and lovingness and gentleness. It may
seem that you have moved from one place to another, but that is
not what happens. If you experience yourself as your real presence,
you just see one thing dissolving into another in the middle of
your presence. If you are identified with the structure, it will
feel as if you are disintegrating, and then there is emptiness,
and then presence arises. This impression is only because your
attention is focused on a certain part of you, and so you are
not experiencing your totality. You do not fall apart or disappear,
although it feels that way if your ego is the part of you that
you are identified with. (Facets of Unity, pg 251)
