Zitat:What separates nocturnal dream-sleep from an actual direct experience of the unconscious layers of mind is a very thin borderline only, and the crossing of this line has been aptly described as ‘the journey to Hades’ [3]. As we know from classical mythology, the intervention of Hades invariably turns the world upside down; now phenomena are seen not only through the eyes of Eros and human life and love, but also through Thanatos: “‘Entering the underworld” refers to a transition from the material to the psychical point of view. Three dimensions become two as the perspective of nature, flesh and matter fall away, leaving an existence of immaterial, mirrorlike images, eidola …the Greek word Eidolon signifying an image [2]. Spare described the state when consciousness has crossed this fine line as Neither-Neither or Inbetween, “not this – nor that”, out of which most notably his automatic drawings rose: “…the ‘Neither-Neither” principle of those two, is the state where the mind has gone beyond conception …The ‘I’ principle has reached the ‘Does not matter – need not be’ state, and it is not related to form. Save and beyond it, there is no other, therefore it alone is complete and eternal [4]. The key to reaching this state is the attainment of a “total vacuity” of the conscious mind which concept is also an important part of Eastern religion such as the Buddhist path to enlightenment or Yoga and Tantra exercise.
