Caves are prevalent images in the world of myths, legends, and cults. The cave is thought to be closely related to the symbolic HEART, and is often a place where the self and ego unite.
They can be secret passageways to an underworld, places in which to make contact with the powers and forces which will eventually make their way into the world of light. As for Jung it represents the security and the impregnability of the unconscious (Biederman, 61). Entering the cave is considered re-entry into the womb of Mother EARTH
