The Structure and Dynamics of the Psyche (Collected Works of C.G. Jung, Volume 8)

Restriction to material reality carves an exceedingly large chunk out of reality as a whole, but it nevertheless remains a fragment only, and all round it is a dark penumbra which one would have to call unreal or surreal.

This narrow perspective is alien to the Eastern view of the world, which therefore has no need of any philosophical conception of super-reality.

Our arbitrarily delimited reality is continually menaced by the “supersensual,” the “supernatural,” the “superhuman,” and a whole lot more besides.

Eastern reality includes all this as a matter of course.

For us the zone of disturbance already begins with the concept of the “psychic.”

In our reality the psychic cannot be anything except an effect at third hand, produced originally by physical causes; a “secretion of the brain,” or something equally savoury.

At the same time, this appendage of the material world is credited with the power to pull itself up by its own bootstraps, so to speak; and not only to fathom the secrets of the physical world, but also, in the form of “mind,” to know itself.

All this, without its being granted anything more than an indirect reality. ~Carl Jung, CW 8, Pages 382-383
