How does Chapter 21 explain the concept that all saints are interconnected, even if they appear in different places and times?

Chapter 21 presents a profound teaching on the unity of saints. It states that although saints may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." The text clarifies that while the country, time, and circumstances may differ, the signs of one saint are completely known to another, and inwardly, they are all one. To illustrate this, the chapter uses an analogy of a sovereign king who establishes outposts in various locations with appointed officers. In the same way, the "Emperor of Self-bliss" appears in different forms as saints, invisibly pulling the strings to manage the kingdom of spiritual welfare, as described in Chapter 21.
