Lecture XVII
When man develops further, when abstract thought itself develops to the stage on which the beings are incarnated who work with us when we speak, then he is a Chela, an occult pupil. To be a Master means: To work in the substance in which the beings are incarnated who work with us in our thoughts. Imagination gives the picture. This is why the great religious teachers of earlier times spoke pictorially, for imagination gives the picture, not abstract thoughts. In all religions, teachings were expressed in pictures. At first the picture is for man something of lesser importance, but when he understands how to form again for himself a picture out of every thought, then he has reached a higher stage. This is the pre-requisite for a quite new kind of perception. Everything depends on a man developing to the point at which he no longer thinks merely abstractly, but at all times has his thoughts in pictures.
