Going into the unconscious also means to go into the collective unconscious we all share. In Greek mythology there was Tartaros, a name originally used for the entire underworld. Tartaros is the psychic world deep in man where all those nasty emotions reside, like the lust for murder and destruction, thirst for blood, fear, hate, revenge, the lust for power, melancholy and so on. It is not easy to admit to oneself, but they all reside in ourselves. Because we don’t like it, we have cut ourselves off from being aware of this dark realm. We have repressed all our dark emotions into this deep realm of Tartaros. This is the heritage of man, dating from ancient times.
