Jung eventually elaborated a pluralistic model of the psyche’s dissociability into many different complexes, each containing an archetypal set of motifs or images at its core. These archetypal images defined a deeper ‘strata’ of the unconscious
This passage identifies the theoretical foundation of archetypal dissociation: Jung’s recognition that traumatic splitting penetrates to the archetypal layer, where universal motifs anchor each complex.
