The artist must be blind to "recognized" and "unrecognized" form, deaf to the teachings and desires of his time. His open eyes must be directed to his inner life and his ears must be constantly attuned to the voice of inner necessity.

The sensations of colors on the palette can be spiritual experiences.

Colors produce a spiritual vibration, the impression they create is important only as a step towards this vibration.

The work of art is born of the artist in a mysterious and secret way. From him it gains life and being. Nor is its existence casual and inconsequent, but it has a definite and purposeful strength, alike in its material and spiritual life.

There is, however, in art another kind of external similarity which is founded on a fundamental truth. When there is a similarity of inner tendency in the whole moral and spiritual atmosphere, a similarity of ideals, at first closely pursued but later lost to sight, a similarity in the inner feeling of any one period to that of another, the logical result will be a revival of the external forms which served to express those inner feelings in an earlier age.

The world is full of resonances. It constitutes a cosmos of things exerting a spiritual action. The dead matter is a living spirit.

As a picture painted in yellow always radiates spiritual warmth, or as one in blue has apparently a cooling effect, so green is only boring.

The true work of art is born from the 'artist': a mysterious, enigmatic, and mystical creation. It detaches itself from him, it acquires an autonomous life, becomes a personality, an independent subject, animated with a spiritual breath, the living subject of a real existence of being.
