The painter goes through states of fullness and evacuation. That is the whole secret of art. I go for a walk in the forest of Fontainebleau. I get 'green' indigestion. I must get rid of this sensation into a picture. Green rules it. A painter paints to unload himself of feelings and visions. People seize on painting to cover up their nakedness. They get what they can wherever they can. In the end I don't believe they get anything at all. They've simply cut a coat to the measure of their own ignorance. They make everything, from God to a picture, in their own image. That is why the picture-hook is the ruination of a painting.
