[...] the really complex and unfamiliar part of the human mind, from which symbols are produced, is still virtually unexplored. It seems almost incredible that though we receive signals from it every night, deciphering these communications seems too tedious for any but a very few people to be bothered with. Man's greatest instrument, his psyche, is little thought of, and it is often directly mistrusted and despised. "It's only psychological" too often means: It is nothing.

Our mind has its history, just as our body has its history. You might be just as astonished that man has an appendix, for instance. Does he know he ought to have an appendix? He is just born with it....Our unconscious mind, like our body, is a storehouse of relics and memories of the past. A study of the structure of the unconscious collective mind would reveal the same discoveries as you make in comparative anatomy. We do not need to think that there is anything mystical about it.

A dream that is not understood remains a mere occurrence; understood it becomes a living experience.

Dreams are symbolic in order that they cannot be understood; in order that the wish, which is the source of the dream, may remain unknown.

Whenever we touch nature we get clean. People who have got dirty through too much civilization take a walk in the woods, or a bath in the sea. Entering the unconscious, entering yourself through dreams, is touching nature from the inside and this is the same thing, things are put right again.

In each of us is another whom we do not know. He speaks to us in dreams and tells us how differently he sees us from the way we see ourselves.

Dreaming is a philogenetically older mode of thought.

The dream arises from a part of the mind unknown to us, but none the less important, and is concerned with the desires for the approaching day.

Knowing your own darkness is the best method for dealing with the darkness's of other people. One does not become enlightened by imagining figures of light, but by making the darkness conscious. The most terrifying thing is to accept oneself completely. Your visions will become clear only when you can look into your own heart. Who looks outside, dreams; who looks inside, awakes.
