The paper discusses the Jung-Pauli mainly unconscious 'collaboration', where the synchronistic background can be highlighted only by Carl Kerényi's 'involvement', that is by the broadening the duo into a trio. The main theme is the interplay of the conscious and the unconscious and one of the main patterns of the 'especial communication' is based on the 'patterns' of the 'Eleusinian Mysteries', on the archetypal image of Mother and Daughter or on its cognition and exploration as a 'dynamic hermeneutical system'. The identification of the conscious and unconscious 'cognitive network' of the 'three hidden pillars', (Jung, Pauli and Kerényi) results an unconscious acausal synchronistic artifact too.
