A technique of focused introspection.
Jung distinguished between meditation practiced in the East or in traditional Western religious exercises, and its use as a tool for self-understanding, particularly in the realization of projections.
If the ancient art of meditation is practised at all today, it is practised only in religious or philosophical circles, where a theme is subjectively chosen by the meditant or prescribed by an instructor, as in the Ignatian Exercitia or in certain theosophical exercises that developed under Indian influence. These methods are of value only for increasing concentration and consolidating consciousness, but have no significance as regards affecting a synthesis of the personality. On the contrary, their purpose is to shield consciousness from the unconscious and to suppress it.["The Conjunction," CW 14, par. 708.]
When meditation is concerned with the objective products of the unconscious that reach consciousness spontaneously, it unites the conscious with contents that proceed not from a conscious causal chain but from an essentially unconscious process. . . . Part of the unconscious contents is projected, but the projection as such is not recognized. Meditation or critical introspection and objective investigation of the object are needed in order to establish the existence of projections. If the individual is to take stock of himself it is essential that his projections should be recognized, because they falsify the nature of the object and besides this contain items which belong to his own personality and should be integrated with it.[Ibid., par. 710.]
