May I repeat what I told you here: treat nature by means of the cylinder, the sphere, the cone, everything brought into proper perspective so that each side of an object or a plane is directed towards a central point. Lines parallel to the horizon give breadth... lines perpendicular to this horizon give depth. But nature for us men is more depth than surface, whence the need to introduce into our light vibrations, represented by the reds and yellows, a sufficient amount of blueness to give the feel of air.
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.
Right now a moment is fleeting by! Capture its reality in paint! To do that we must put all else out of our minds. We must become that moment, make ourselves a sensitive recording plate. give the image of what we actually see, forgetting everything that has been seen before our time.
