Based on Chapter 21, what is the relationship between different Saints, and how do they operate in the world?

Chapter 21 explains 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 emphasizes that inwardly, all Saints are one, and the signs of one are completely understood by another. The author uses an analogy to clarify this concept, comparing the divine system to a sovereign king who establishes outposts in various locations with appointed officers to maintain order. In the same way, the 'Emperor of Self-bliss' appears in various places, acting as these divine outposts, invisibly pulling the strings and driving the chariot of His spiritual kingdom across the world.
