Your work will be, in the last analysis, what you yourselves are. Let no sophistry blind you to the truth of that. There are rhythms in the world of space which we find only in the architecture of the past, and enamoured of their beauty we repeat them over and over (off the key for the most part), on the principle that all the songs have been sung; or we just make a noise, on the principle that noise is all there is to architecture anyway. It is not so. Those systems of spatial rhythms which we call Egyptian, Classic, Gothic, Renaissance architecture and the rest, are records all of the living human spirit energizing in the stubborn matter of the physical plane with joy, with conviction, with mastery. When that undying spirit awakes again in you, stirred into consciousness by meditation, which is its prayer; by music, which is its praise; by the contemplation of that fair form which is its temple; and by communion with nature, which is its looking-glass; you will experience again that ancient joy, hold again that firm conviction, and exercise again that mastery to transfuse the granite and iron heart of the hills into patterns unlike any that the hand of man has made before.
