While Mark creates his own physical image, you do not see it. At this time, there are three entirely different Marks in this room. ・・・There is the Mark which Mark has created, an actual physical construction. There is another, created by you, Joseph. There are two more physical Marks, one created by Ruburt, and one by your cat. If another person entered the room, there would be still another physical Mark. In this room, then there are four physical Ruburts, Four physical Josephs, and four physical cats. There are indeed four rooms.
