Malleability
The property of malleability has a different significance than
that of changeability. The soul cannot only change herself, she
can be changed. She can be molded by her experiences, whether
they have an external or internal origin. The forms she assumes
are not always her choice; they can be imposed on her. At first,
this may appear to be an innocent property, necessary for her
in order to respond to situations and external stimuli. The forms
she assumes are frequently dictated by external stimuli; her senses
reflect the external environment by generating corresponding inner
forms, and she also responds with corresponding inner feelings
and thoughts to various environmental stimuli… the fact
that the soul inhabits a world means that her inner forms are
constantly shaped by external impacts. This shaping is necessary
for learning and action. However, the soul’s malleability
also allows the impact of the world to mold her more than is necessary
for learning and action. By malleability we mean not only pliability;
we also mean that she can be shaped into a relatively permanent
form, fixed beyond her normal needs for perception, learning,
and action. (Inner Journey Home, pg 94)

Thus, ego development occurs mostly through the establishment
of relatively fixed impressions. Furthermore, because ego development
culminates in the establishment of an identity and sense of self
that depend on the fixed impressions, it naturally leads to a
limitation on our malleability and impressionability; dependence
on the fixed impressions orients us toward identification with
and attachment to them. We tend to perpetuate our self and its
identity, limiting our openness, malleability, and impressionability.
We generally experience as threatening and destabilizing the forms
of experience outside the boundaries of our identity. In other
words, we become both habituated and attached to the fixed impressions
that compose our identity, at the expense of our basic capacities
of openness, malleability and impressionability. (Inner Journey
Home, pg 102)
