How does Chapter 21 explain the relationship between different saints who may appear in different places and times?

Chapter 21 presents the profound concept that all saints are "inwardly, they are all one" and "essentially inseparable from one another." Although they may take incarnations in different places and at different times for specific purposes, their core essence is united. The chapter uses an analogy to clarify this: just as a sovereign king establishes outposts with officers to manage his kingdom, the "Emperor of Self-bliss" (referring to the divine principle) appears in various forms like Sai Baba, invisibly pulling the strings to guide His spiritual kingdom. This implies a hidden, divine arrangement where one saint fully knows the nature of another.
