Maurice Maeterlinck said this quote

Look upon men and things with the inner eye, with its form and desire, never forgetting that the shadow they throw as they pass by, upon hillock or wall, is but the fleeting image of a mightier shadow, which, like the wing of an imperishable swan, floats over every soul that draws near to their soul. Do not believe that thoughts such as these can be mere ornaments, and without influence upon the lives of those who admit them. It is far more important that one’s life should be perceived than that it should be transformed; for no sooner has it been perceived, than it transforms itself of its own accord.
