"The artist must train not only his eye, but his soul."
"Colour is the keyboard, the eyes are the hammers, the soul is the piano with many strings. The artist is the hands which plays touching one key or another purposively to cause vibrations in the Soul."
"There is no form, there is nothing in the world which says nothing. Often - it is true - the message does not reach our soul, either because it has no meaning in and for itself, or - as is more likely – because it has not been conveyed to the right place.. ..Every serious work rings inwardly, like the calm and dignified words: ‘Here I am!'"
