As a psychoanalyst, I began to recognize that many harsh and wonderful emotions build on remembered feeling which may begin in preverbal existence.  The cooing and loving touch of a mother  and father vs the fears worries and outright hostilities of a parent.  These remembered feeling get triggered and further constructed by similar instances in verbal life.  It seems that the mind is like outerspace, we will never know fully how it operates as it is too much for humans to completely understand.
