How does Chapter 21 describe the relationship and unity between different Saints?

Chapter 21 explains that Saints, despite appearing at different times and in different places, are fundamentally one and work together through a secret arrangement. The text states that while the country, time, and objects may differ, the signs of one Saint are completely known by another, and "Inwardly, they are all one." It uses a powerful analogy, comparing this system to a sovereign King who establishes outposts in various places to maintain order. In this metaphor from Chapter 21, Sai Baba is described as the "Emperor of Self-bliss," who appears in various forms and invisibly pulls the strings to guide His kingdom.
