Repression
The individual, in other words, learns to approve of in himself
what his parents approved of, and to disapprove of what they disapproved
of. What is disapproved of becomes mostly pushed out of consciousness,
relegated to the unconscious; and so these defense mechanisms
are ultimately forms of repression, as Freud articulated. For
this repression to be done effectively, the whole operation becomes
unconscious; i.e., both the ego defense mechanism and the corresponding
coercive parts of the superego become unconscious. (Work on the
Superego, pg 3)

Sigmund Freud discovered that the human individual manages to
develop in spite of early intolerable difficulties by avoiding
awareness of them through various methods of repression. This
repressed material does not disappear but remains hidden in what
he termed the unconscious, exerting a powerful force on conscious
experience, actions, and dreams. One of the momentous discoveries
of modern psychology, this made it possible to engage in therapeutic
psychodynamic work, which is the retracing of conflictual and
painful manifestations and symptoms to their unconscious roots,
and then releasing the early conditioning. The ancient wisdom
traditions did not have this understanding; hence their psychologies
and methods could not and did not deal with this level of barriers
to the soul’s liberation and realization. (Inner Journey
