Inner Mother
We can say then that the Merging Essence is in a sense the "inner
mother." In fact, all students in the process of inner realization
relate to it as if it were their good mother. One of the main
issues to be worked through is that of associating it with one's
mother. It is an independent aspect of Essence, a Platonic form.
It has its own perspective, or rather; one can see all of reality
from its vantage point. One can see the whole process of human
development as the ever-increasing merging with one's Being, as
more and more boundaries are dissolved. (The Pearl Beyond Price,
pg 243)

Merging Essence and mother's image
Thus we can see that the internalization of the mother's image
is an incomplete attempt to integrate the Merging Essence. When
the metabolism is complete, the nondifferentiated representations
are absorbed into Being, resulting in the realization of the Merging
Essence. Thus, when both the Personal Essence and the Merging
Essence are realized, the Personal Essence takes the place of
the separate individuality, and the Merging Essence takes the
place of the mother's image. (The Pearl Beyond Price, pg 241)
