When that amusing "Pauli effect" of the overturned vase occurred, on the occasion of the founding of the Jung Institute, I had the immediate and vivid impression that I should "pour out water inside" (— to use the symbolic language that I have acquired from you).

Letter to Carl Jung (16 June 1948), referring to an incident where a vase fell over, apparently spontaneously as he entered a room, and an essay: Moderne Beispiele zur 'Hintergrunds-physik' (Modern Examples of 'Background Physics' ). Jung and Pauli worked together in developing theories of Synchronicity.
