One might ask to what extent the jinn world and the angelic world occupy space in our world and pervade it. But what is space? Space is that which accommodates. The mind is a space also, a space which is wider than the world. Our eye is a space too; and as the mind does not mean the brain, so the space in the eyes of our body is not the only space; behind it is another space which is connected with it. And when this idea becomes clear to man, that there is another space, different from this outer space which already accommodates so much, then the vision of the heavens is opened before him.
