How does Chapter 21 explain the relationship between different Saints, like Sai Baba and others?

Chapter 21 presents the idea that all Saints are fundamentally interconnected, despite appearing at different times and places. The text explains that they are "essentially inseparable from one another" and that "inwardly, they are all one." It uses an analogy where Sai Baba is the "Emperor of Self-bliss" who establishes outposts, which are other Saints, in various places to manage His kingdom. This secret arrangement ensures that although their external circumstances like country and time may differ, the signs of one Saint are completely understood by another, as they all work together invisibly.
