What analogy does Chapter 21 use to explain how Saints manage their spiritual work across the world?

Chapter 21 employs a powerful analogy of a sovereign king's empire to explain the workings of Saints. It compares a great Saint to an "Emperor of Self-bliss" who, like a worldly king, establishes outposts in various places. In this analogy, other Saints act like appointed officers in these outposts, ensuring the prosperity and order of the spiritual kingdom. According to the description in Chapter 21, this Emperor invisibly pulls the strings from afar, driving the chariot of His kingdom. This illustrates how Saints, though geographically separate, operate within a single, coordinated divine administration.
