Merging Love
This aspect is present from the beginning of life but dominates
especially between two and ten months of age. This period of life
generally coincides with the period of ego development, called
the symbiotic phase by Margaret Mahler… In this state of
ego development, the child is not aware of the mother or himself
as separate individuals in their own right. The ego has not separated
out. Mother and self are still a unity - a dual unity. In infant
observation we find that when the infant experiences the dual
unity without any frustration or conflict, his essential state
is that of merging love. It is a pleasurable, sweet, melting kind
of love. The baby is peaceful, happy and contented. (Essence,
pg 92)

Whenever there is any loss of the symbiotic union, the dual unity
with mother, the child experiences the loss of merging Essence.
To repeat, this is because, for him, the merging love aspect of
Essence is he and his mother together. (Essence, pg 93)

We can see that the merging love issue is one of the main unconscious
determinants motivating adults toward intimate love relationships
and is also the reason behind many of the difficulties in relationships.
It is well known in depth psychology that people see their mothers
in their love partners. This happens, of course, because individuals
deeply feel and believe that their incompleteness will be eliminated
and their longing will be satisfied by regaining the gratifying
merged relationship with the mother, now displaced to a person
of the opposite sex. (Essence, pg 96)
