No doubt the angels are primarily for the angelic heavens and the jinns for the sphere of the jinn, yet in a house the inhabitants of the second or third floor are sometimes sent to the ground floor on an errand when it is necessary. The most remarkable thing that one notices in all those planes of existence is that the beings of these separate planes are not imprisoned there by the Creator. They become captive themselves, just as a man who lives in a village passes his whole life in the same place, and when he is told of the history of the neighboring county it is another world to him. He never tries to leave his village, and the neighboring county is foreign to him. He has heard the name of the next village all through his life, but he has never tried to visit it.
