How does Chapter 21 explain the idea that all Saints are interconnected?

Chapter 21 explains that Saints, despite appearing at different times and in various places for specific purposes, are essentially inseparable and inwardly one. The text uses an analogy to clarify this concept, comparing the spiritual realm to a kingdom. It describes an "Emperor of Self-bliss" who establishes outposts in different places, appointing Saints as His officers. These Saints, like regional governors, manage the affairs of this spiritual kingdom, invisibly pulling the strings. As stated in Chapter 21, though their external circumstances like country and time may differ, the signs of one Saint are completely known by another, confirming their fundamental unity.
