As 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 Lévy-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.

We are living in what the Greeks called the kairos - the right moment - for a 'metamorphosis of the gods', of the fundamental principles and symbols. This peculiarity of our time, which is certainly not of our conscious choosing, is the expression of the unconscious man within us who is changing.

Dream analysis stands or falls with [the hypothesis of the unconscious]. Without it the dream appears to be merely a freak of nature, a meaningless conglomerate of memory-fragments left over from the happenings of the day.

People will do anything, no matter how absurd, to avoid facing their own souls.

The problem of synchronicity has puzzled me for a long time, ever since the middle twenties, when I was investigating the phenomena of the collective unconscious and kept on coming across connections which I simply could not explain as chance groupings or "runs." What I found were "coincidences" which were connected so meaningfully that their "chance" concurrence would represent a degree of improbability that would have to be expressed by an astronomical figure.

The squaring of the circle is a stage on the way to the unconscious, a point of transition leading to a goal lying as yet unformulated beyond it. It is one of those paths to the centre.

I am this bundle of what has been, and what has been accomplished.
