Self-Image
This self-image, this psychic structure, is nothing simple or
superficial. It is complex and profound, and the identification
with it is just as profound. For our purposes, however, it is
crucial to remember that regardless of how completely the self-image
has become part and parcel of one's sense of self, it is nevertheless
simply a construct in the mind. (The Pearl Beyond Price, pg 25)

Self-image and boundaries
After consolidation, the self image not only gives the individual
his sense of personal identity, but it determines more than anything
else his subsequent experience of himself, his life, and his environment.
It determines his sense of being, his inner experience, and everything
else about him. The self-image is constituted, as Mahler says,
of self-boundaries: not only spatial boundaries, but all the boundaries
that determine the range of the individual's experience, perception,
and actions. For example, if an individual has a self-image of
being weak, he will tend not to do things that he believes require
strength. Likewise, a self-image of being stupid will inhibit
a person from learning things that he believes require intelligence,
so that he will actually not understand and will behave in a stupid
way when confronted with such things. (The Void, pg 14)

Self-image and emptiness
The structuralization of self-image, as well as other childhood
experience, leads to the loss of space as part of our experience.
Along with space, and due to other factors, Essence in its various
aspects is lost. Self-image ends up excluding emptiness and the
fullness of Essence as possible categories of experience. (The
Void, pg 86)

Self-image and Essence
This is where Essence is valuable; it will give you the knowledge
and understanding that no one else can. If you deeply investigate
the issue of self-image, you'll come to the essential aspect that
corresponds to self-image. When this happens, you will experience
Essence in a way that has no self-image; instead there will be
space, openness, inner spaciousness. This is the essential aspect
that was lost when you developed the self-image and believed that
the self-image was who you truly are. The self-image always has
a boundary -- physical, emotional or conceptual. When you experience
space, you experience yourself as being without boundaries, without
definition, just openness. (Diamond Heart Book 2, pg 36)

Self-Object
The self-object is an object that is not seen by the self as
completely separate from the self. (The Void, pg 121)
