Man wishes to know about God, about heaven, about the things unknown, and about the world unseen, and he thinks he can see them from the first floor. He is not ready to believe there is anything on the seventh floor; he thinks there is no such thing as a seventh floor, nothing but the first. If he were freed from this delusion, and if he were allowed to go to the other floors, then he would be able to see what the fourth, fifth, sixth, and seventh floors contain. And then he would know there is something through which one can gain a knowledge of past, present, and future.
