There was a king who created, through his magical art, barriers and walls, one within the other, with which to surround himself. All these were, however, really illusory. He commanded that money be spread around at the gates of each of these walls to see how great the determination and desire of his subjects, how much effort each one of them would make, to come to the king.
There were those of his subjects who immediately returned home after they had collected a little money at the gates of these illusory walls. There were others who got as far as the second or third walls. But there were very few who did not desire to collect merely physical treasures, only to reach the king himself.
After considerable effort they came to the king and saw that there were really no barriers and walls, everything was a magical illusion.
So it is with God. Those who truly understand know that all the barriers and walls of iron, all the garments and coverings are really on God himself in hiding, as it were, because there is no place where he is not.
