Lend your ears to music, open your eyes to painting, and … stop thinking! Just ask yourself whether the work has enabled you to walk about into a hitherto unknown world. If the answer is yes, what more do you want? 

The more frightening the world becomes … the more art
becomes abstract.

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 colours, and that you be a true poet. This last is essential.

— Wassily Kandinsky
