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

Chapter 21 explains that Saints are 'essentially inseparable from one another' and that 'inwardly, they are all one.' While they may take incarnations in different places and times for specific purposes, their underlying spiritual essence is unified. The text uses an analogy to clarify this concept: just as a sovereign king establishes outposts with appointed officers to manage his kingdom, the 'Emperor of Self-bliss' has Saints appearing in various places to 'drive the chariot of His kingdom, pulling the strings invisibly.' This chapter teaches that one Saint fully knows the signs of another, highlighting their secret, interconnected arrangement.
