The more we idealize the past and refuse to acknowledge our childhood sufferings, the more we pass them on unconsciously to the next generation.
Without realizing that the past is constantly determining their present actions, they avoid learning anything about their history. They continue to live in their repressed childhood situation, ignoring the fact that is no longer exists, continuing to fear and avoid dangers that, although once real, have not been real for a long time.
There are people who have benefited from therapy without being confronted with the past at all.
