For the present at least [1909] I shall restrict my work to the ordinary world of the senses, since that is the world in which we still live. But nevertheless art even now form a transition to the finer regions, which perhaps I am incorrect in calling spiritual, for everything that has form is not yet spiritual, as I read somewhere. But it is nonetheless the path of ascension away from matter. Well dear Querido, with many heartfelt wishes, Piet Mondriaan.
