The fingers must be educated, the thumb is born knowing.

When I am finishing a picture, I hold some God-made object up to it - a rock, a flower, the branch of a tree or my hand - as a final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there's a clash between the two, it's bad art.

Everything in art must spring from the movement of our whole life-stream, of our whole being - including the unconscious.

Mozart never composed anything, ever! He copied what was written on his soul.

Art is foremost a state of mind, and only secondarily a problem of form.

If I create from the heart, nearly everything works; if from the head, almost nothing.

What I mean by 'abstract' is something which comes to life spontaneously through a gamut of contrasts, plastic at the same time as psychic, and pervades both the picture and the eye of the spectator with conceptions of new and unfamiliar elements.
