The self is the hero, threatened already at birth by envious collective forces; the jewel that is coveted by all and arouses jealous strife; and finally the god who is dismembered by the old, evil power of darkness.
Jung identifies the jewel as a direct symbol of the Self in its archetypal heroic aspect, endangered by collective opposition and equivalent to the dismembered god.
