233. With regard to the science of this world, its most eminent representatives have now reached a zone where one can begin to see that there is no real "fixed point" in the physical world, but that everything is movement and that all happenings and all sensing constitute different forms of understanding that movement. If material realities, meaning all created things, are the same as movement and movement is the same as transformation, all created things are subject to constant change. The impression which one object or another gives to an observer is thus only a temporary link or nuance in the movement or change to which that object is inextricably subject. In the very next instant that object has undergone a change. This change can be great or it can be small, so small that it is microscopic or physically invisible, but that does not hinder the fact that the change is nevertheless there. There is no created thing which is absolutely the same today as it was yesterday and still less so is it the same as it was the day before yesterday. And the further we go back in time the greater the difference between the present and the past appearance of that created thing. But the process of transformation continues and this created thing's condition and appearance today will, in the same way, be different from its condition and appearance in the future. As the faculty of sensing is dependent on organs - which are also synonymous with combined energies or movements and thereby subject to change - then, from a cosmic viewpoint, the individual will be quite unable to see that created thing twice in just the same way, for the sense-organs in the interval between the first and second time have changed and that change must have left its mark on the individual's last experience, which thereby would necessarily present itself as correspondingly divergent from the first experience of that same thing. That these changes can be of a microscopic nature and on that account escape the individual's physical sensing or observation does not alter the fact. For the occult or cosmic sight the change has taken place.
