Human beings will make important discoveries in the future in this respect. They will actually unite their moralspiritual nature with the results of sense perception. An infinite deepening of the human soul can be foreseen in this domain. Let us pick a particular example to start from. We will simply imagine that we are looking at a surface shining all over with the same shade of strong vermilion, and let us assume we succeed in forgetting everything else around us and concentrate entirely on experiencing this colour, so that we have the colour in front of us, not merely as something that works upon us but as something with which we ourselves are united, that we are within. You will then be able to feel as though you were in the world, and in this world the whole of you has become colour, the whole of your innermost soul, and wherever your soul goes in the world you will be a soul filled with red, living in, with and out of red. Yet you will not be able to experience this intensely in the soul unless the corresponding feeling is transformed into moral experience, real moral experience.
