The universe is a vast, constantly working factory and the globe of the earth a hostel  and guesthouse which is continually filled and emptied. Generally, factories, hostels and  guesthouses which are thus used become much dirtied and soiled with filth, debris and  rubbish, and putrid matter accumulates in all parts of them. They cannot be occupied unless  they are kept with care and cleaned and swept; human beings are overwhelmed by the dirt. The factory of the universe and guesthouse of the earth,  however,  are  totally  pure,  clean   and  spotless,  and  completely  unsoiled, untainted  and  fresh;  there  is  nothing  unnecessary,  nothing  without  benefit,  not  a random piece of dirt to be found. Even if there is apparently, it is quickly thrown into a transformation machine and cleaned.

This means that the One who looks after this factory does so very well. Its Owner is such that He sweeps and cleans and orders the vast factory and extensive palace as though they were small rooms. Considering the size of the huge factory, there is no dirt or rubbish remaining from its filth and debris. Indeed, its cleanness and tidiness are remarkable.

If someone does not wash himself and clean his small room for a month, they will  become extremely dirty and soiled. That is to say, the cleanliness, purity, and luminosity in  this palace of the world arise from a continuous, wise, and diligent cleaning. If it were not for this cleaning, sweeping and careful tending, in one year all the hundred thousand animal species would have been choked on the face of the earth.

Also, the debris of the globes in space and the heavens, which manifest life and death, and of satellites and stars, would have smashed not only our heads and those of the other animals, but also the head of the earth itself and of our world. They would have rained down on our heads rocks the size of mountains and driven us away from our homeland in this  world.  However, for a long time past, if as a warning a few meteorites have fallen as  a  result of destruction and reconstruction in those lofty worlds, they have not broken any heads.

Furthermore, the corpses of a hundred thousand animal species and the debris of two hundred thousand plant species each year on the face of the earth resulting from the alternation and struggles of life and death would have so utterly filthied the land and the sea that conscious creatures, rather than loving and delighting in the face of the earth, would have felt disgust and aversion at such ugliness and fled to death and non-existence.

Just as a bird cleans its wings with ease and a scribe his pages, so too the wings of the aircraft of the earth and the birds of the heavenly bodies and the pages of the book of the universe are cleaned and made beautiful. So much so that people who do not consider the infinite beauty of the hereafter and think with belief become lovers of this cleanliness and beauty of the world, they worship it.
