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

Chapter 21 puts forth the teaching that all Saints are fundamentally interconnected and unified. The text explains that while Saints may take incarnations in different places and times for specific purposes, they are "essentially inseparable from one another." It further clarifies that "inwardly, they are all one," and the signs of one Saint are completely known by another. This unity is compared to a sovereign king's outposts, suggesting a divine, coordinated network. Sai Baba is referred to as the "Emperor of Self-bliss," who invisibly manages His kingdom through these various saintly manifestations.
