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

Chapter 21 explains that all Saints are fundamentally interconnected and essentially one, despite appearing in different locations, times, or forms. The text states that while their country, time, and objects may differ, the signs of one saint are completely known by another, and "Inwardly, they are all one." To illustrate this, an analogy is used of a sovereign king who establishes outposts in various places with officers to maintain order. Similarly, Sai Baba, described as the "Emperor of Self-bliss," appears in various places and invisibly pulls the strings of his spiritual kingdom. This reveals a secret arrangement where Saints work in unison for a specific purpose, even if they seem separate to the outside world.
