What are surface features in the spirit land?

In the spirit land objects on the horizon do not vanish in the same way, as surface features do on earth (the earth and sky meeting as one). Instead the sky is seen as a vast canopy overhead, and the circles above seem like plateaux resting on mountain tops. On reaching those mountains and seeing the new country spread out, there is always on its horizon again more mountains and fresh lands lying higher―a succession of terraces, each leading to a lower and less beautiful one until the earth plane is seen surrounding the earth itself, and then beyond that again lie another succession of terrace-like lands leading down to Hell. Thus, circle melts into circle and sphere into sphere, only that between each sphere a barrier of magnetic waves exist, which repels those from a lower sphere who seek to pass it until their condition comes in harmony with the higher sphere.
