I think this was one Jung's main ideas. And that tending to our spiritual side is import for good health mentally,,and that the psyche is designed to go thru a maturation process toward wholeness, at what ever level it of consciousness it can reach and that level in some way effects the entire human collective of consciousness/unconscious.
The World comes into existence by being made known,, the whole evolution of mankind and way of thinking consciously has been in that direction ever since we ate the forbidden fruit of consciousness it's evolution is like a macrocosm of the microcosm that goes on with each individual human.
