Shut your eyes, wait, think of nothing. Now, open them … one sees nothing but a great coloured undulation. What then? An irradiation and glory of colour. This is what a picture should give us … an abyss in which the eye is lost, a secret germination, a coloured state of grace … loose conciousness. Descend with the painter into the dim tangled roots of things, and rise again from them in colours, be steeped in the light of them.
