There is no must in art because art is free.
All methods are sacred if they are internally necessary. All methods are sins if they are not justified by internal necessity.
The artist must train not only his eye but also his soul.
The more frightening the world becomes ... the more art becomes abstract.
An empty canvas is a living wonder.. far lovelier than certain pictures.
The artist is not a 'Sunday child' for whom everything immediately succeeds. He does not have the right to live without duty. The task that is assigned to him is painful, it is a heavy cross for him to bear.
Abstract art places a new world, which on the surface has nothing to do with 'reality,' next to the 'real' world.
Of all the arts, abstract painting is the most difficult. It demands that you know how to draw well, that you have a heightened sensitivity for composition and for colors, and that you be a true poet. This last is essential.
