Inner Space
Inner spaciousness is the necessary step for the emergence of
Being in the essential manifestation of support for nondoing.
It usually manifests as an experience of Presence in a new form,
which has the characteristics of solidity, immensity, immovability,
strength, groundedness, definiteness, precision, and clarity.
We feel solid, as immense as a mountain, as immovable and grounded
as a column, but as clear and definite as a cut diamond. We have
the innate certainty that we can be, for we are, simply and easily.
There is an implicit confidence in our capacity to be ourselves
and the determination about and commitment to it. The psychological
feeling is that of a singular and clear recognition of support
-- of our own inner support. But it is not our own in terms of
ownership; we perceive that it is inseparable from the Being that
we now recognize as our self. We may feel supported, we may feel
the presence of support, or we may feel that we are support. (The
Point of Existence, pg 259)

Inner space and spatial extension
Inner space is, of course, not the usual physical space, and
is not tied only to body images. It is affected by self-boundaries
that are more emotional and psychological in nature. There is
a correspondence on the ontological level to the relation between
the self-image and the body-image. In other words, just as the
self-image includes body-image in object relations theory, so
in the experience of space, inner psychological space includes
the notion of space as spatial extension. (The Void, pg 30)

This notion of space as openness in more dimensions than the
spatial will help us to construct a theory about inner space and
self-image. First, however, we must say more about this new notion
of space. As the experience of space repeats, deepens, and expands
in the gradual process of dissolving self-boundaries, the individual
becomes aware of more subtle kinds of boundaries. He becomes aware
of and can dissolve boundaries regarding the depth and extent
of his feelings, the kinds and types of feelings and sensations
he can have, the extent of his awareness of both mind and body,
and the categories of possible experiences of himself and the
world. (The Void, pg 31)

Space is the reflection of nonbeing in manifestation. Because
we do not understand the paradoxical nature of true nature, as
a coemergence of being and nonbeing, we conceptualize nonbeing
as space and being as manifesting forms. Just as our ignorance
of the timeless flow and unfoldment of the logos leads to our
conceptualizing time to account for the changes brought about
by this unfoldment, our ignorance of the spaceless nonbeingness
of true nature leads to our conceptualizing space to account for
the accommodating openness made possible by the emptiness of the
absolute. (Inner Journey Home, pg 397)
