Personalization
So the development of the Personal Essence, through the personalization
of essential aspects, is actually a change in the qualitative
character of the personality, and hence is bound to be resisted
by the established self of ego, which is closely related to it.
This personality character is largely the outcome of the process
of ego integration and organization, reflected in one's self-image
and inseparable from the various defensive operations of the ego.
Thus the process of personalization confronts the individual with
very deep anxieties, vulnerabilities and conflicts that he would
usually rather forget for good. (The Pearl Beyond Price, pg 343)

Personalization of Essence
The realization of the Personal Essence can be seen as the attainment
of individuation on the essential level. The consciousness of
the individual has now integrated itself not only as a living
Presence but also as a personal living Presence. It can experience
itself as a person of Being, instead of only as a person defined
by ego identifications. This consciousness can now integrate itself
further by integrating the other aspects of Essence into the presence
of the Personal Essence. (The Pearl Beyond Price, pg 341)

Each aspect becomes so deeply integrated that it is no longer
experienced as part of oneself, but as oneself. In other words,
each aspect becomes absorbed into the Personal Essence. This process
is the gradual development of the Personal Essence. It retains
the qualities and capacities of each aspect, as the latter is
absorbed into it. We refer to this process as the personalization
of Essence, because each essential aspect becomes personal as
it is integrated and absorbed into the consciousness as a further
development of the Personal Essence. Joy becomes a personal Joy,
Peace becomes a personal Peace, Truth becomes a personal Truth,
and so on. (The Pearl Beyond Price, pg 341)
