What is the meaning of spiritual home?

Our spiritual home has its spheres—or belts, which surround and separate each from the other—or it may be called chemical atmosphere, causing a separation from earth and from each sphere, yet being connected by electric and magnetic forces. To explain, we are, as you have been told by other spirits, in separate spheres, with spaces intersecting each other—every space supplied with matter to sustain elements necessary for the requirement of such circle or sphere. Those who are within a certain sphere are surrounded by a belt, holding them absolutely aloof from others—none passing, only through permission or aid of guides who deem them sufficiently harmonised to adapt themselves to the laws of that sphere.
