certain traditions assert that the Cosmic Man is the goal of creation, but the achievement of this should not be understood as a possible external happening… it is not so much that the external world will one day dissolve into the original Great Man, but that the ego’s extraverted orientation toward the external world will disappear in order to make way for the Cosmic Man.
Jung’s school explicitly defines the Cosmic Man not as an eschatological external event but as an inward psychological transformation in which the ego merges into the Self.
