11:7.6

There is an upper and a lower limit to horizontal space with reference to any given location in the universes. If one could move far enough at right angles to the plane of Orvonton, either up or down, eventually the upper or lower limit of pervaded space would be encountered. Within the known dimensions of the master universe these limits draw farther and farther apart at greater and greater distances from Paradise; space thickens, and it thickens somewhat faster than does the plane of creation, the universes.
