The ego is just the tip of the iceberg, a fragment that thinks it’s a whole; the individual is deeper and broader than the ego, as the iceberg is deeper and broader than the tip. But the ego doesn’t always recognise this, so everything that it doesn’t recognise as “self” must be “other”, and so the unconscious is projected outside. Once the ego learns a bit of humility it’s limits can be punctured and then begins the work of integration.
When we are “educated” (read conditioned) all those unwanted qualities get hidden in the unconscious, and rest there until rediscovery. Perhaps confidence was buried; perhaps gentleness was hidden; perhaps curiosity and creativity were deftly swept under the carpet. And we learn to live with this and get on with our lives, even if we feel unsatified with our lot. We have within us treasures awaiting discovery.
Also, the ego interferes with the unconscious as it tries to impose itself on the world within and also the world without, but cutting itself off from its treasures hidden in the unconscious – until it can learn a bit of humility and learn that it belongs to something deeper, higher and wider than itself. Then the conscious and unconscious can become well functioning parts of a whole that is the Self in the process of Individuation.
