Chapter 21 talks about how different Saints are connected. What is the main idea here?

Chapter 21 of the Sai Satcharitra explains the profound concept that all Saints are fundamentally connected, being "inwardly all one." The text clarifies that although they may appear in different countries, at different times, and in various forms to fulfill specific purposes, they are "essentially inseparable from one another." The author uses the analogy of a sovereign king who establishes outposts with appointed officers to manage the kingdom. Similarly, as this chapter explains, Sai Baba, the "Emperor of Self-bliss," and other Saints are like these officers, invisibly pulling the strings and driving the chariot of their spiritual kingdom from different locations.
