I use [Heraclitus' discovery of] enantiodromia for the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, onesided tendency dominates conscious life; in time an equally powerful counterposition is built up, which first inhibits the conscious performance and subsequently breaks through the conscious control.
Carl JungThe Self then functions as a union of opposites and thus constitutes the most immediate experience of the Divine which it is psychologically possible to imagine
Carl JungAs soon as the dialogue between two people touches on something fundamental, essential, numinous, and a certain rapport is felt, it gives rise to a phenomenon which Lรฉvy-Bruhl fittingly called participation mystique. It is an unconscious identity in which two individual psychic spheres interpenetrate to such a degree that it is impossible to say what belongs to whom.
