To become acquainted with oneself is a terrible shock.

A man who has not passed through the inferno of his passions has never overcome them. They then dwell in the house next door, and at any moment a flame may dart out and set fire to his own house. Whenever we give up, leave behind, and forget too much, there is always the danger that the things we have neglected will return with added force.

A man's hatred is always concentrated upon that which makes him conscious of his bad qualities.

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.

Like the sea itself, the unconscious yields an endless and self-replenishing abundance of creatures, a wealth beyond our fathoming.
