46:2.7

The manufacturing or laboratory sector of Jerusem is an extensive domain, one which Urantians would hardly recognize since it has no smoking chimneys; nevertheless, there is an intricate material economy associated with these special worlds, and there is a perfection of mechanical technique and physical achievement which would astonish and even awe your most experienced chemists and inventors. Pause to consider that this first world of detention in the Paradise journey is far more material than spiritual. Throughout your stay on Jerusem and its transition worlds you are far nearer your earth life of material things than your later life of advancing spirit existence.
