How does Chapter 21 explain the relationship between different Saints, even if they live in different places or times?

Chapter 21 presents the teaching that all Saints are fundamentally interconnected and work together through a "secret arrangement." The text states that while they may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." An analogy is used to clarify this: just as a sovereign king has outposts in various places, the "Emperor of Self-bliss" (God) appears in different forms as Saints to manage His kingdom, pulling the strings invisibly. The chapter emphasizes that though country, time, and objects may differ, the signs of one Saint are fully known to another because, inwardly, they are all one.
