What does Chapter 21 say about how different Saints are related to each other, even if they live in different places or times?

Chapter 21 explains that all Saints are essentially one and inseparable, despite appearing in different times, countries, and forms for specific purposes. The text uses an analogy to clarify this, comparing the divine to a sovereign king, the "Emperor of Self-bliss," who establishes outposts in various places. As this chapter describes, the Saints are like the officers appointed in these outposts, all working invisibly to drive the chariot of the divine kingdom. The chapter emphasizes that the signs of one Saint are completely known by another because, inwardly, they are all one.
