What analogy does Chapter 21 use to describe how Saints operate in the world?

Chapter 21 employs a powerful analogy involving a king and his kingdom to explain the coordinated work of Saints. It compares the divine authority to a sovereign king, or an "Emperor of Self-bliss." This emperor establishes outposts in various places and appoints officers to maintain prosperity and order. In the same way, this divine Emperor appears in different forms as Saints in various locations. These Saints, as described in the chapter, act as the appointed officers who drive the "chariot of His kingdom," invisibly pulling the strings to manage the spiritual affairs of the world.
