- Ego, our conscious mind;
- The personal unconscious, forgotten or suppressed memories from our own personal lives;
- The collective unconscious, the collective memory of human thought and experience, from ancient to modern times. This includes the basic human instincts and the archetypes.
Concerning method, for his patients, Jung used psychoanalysis; for himself, he used meditation and his own dreams (the subject of meditator's vivid dreams I shall tackle in a future post). What is interesting to me is that his three-part construct of human psyche was empirically (in the nature of psychological perception) determined. It was true to him and apparently cross-referenced to be true to his students and/or fellow practitioners or inquirers of the subject matter (perhaps including Zen master Charles Luk, translator of Taoist Yoga, whom Jung knew personally). Such details however had not be documented, i.e. these are only my own reasoned analysis or speculation.
More interesting is that such construct can be used (and apparently was/is being used) by students of the subject as a facilitative tool to guide their inner quest through meditation (and vivid dream analysis too, for some). My contention is that Jung's method is also relevant to Taoist and Zen practitioners, for them tools are just transient objects that need to be thrown away after the next stage of Tao/Zen enlightenment is achieved. Besides for an average educated intelligent modern man, a belief in a psyche construct (like Jung's) of good academic standing looks more palatable to his (conscious) mind than accepting the existence of mythical beings of the some Hindi tradition or colorful Lamaist mandalas, not to mention the seemingly unapproachability of some gurus in trance states!
