According to Chapter 21, what is the underlying connection between different saints?

Chapter 21 explains a profound concept about the interconnectedness of saints. It states that although saints may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." The text uses an analogy, comparing them to outposts of a sovereign king, with Sai Baba being the "Emperor of Self-bliss" who invisibly pulls the strings. The chapter emphasizes that the signs of one saint are completely known by another and that inwardly, they are all one, working as part of a secret divine arrangement. This union, however, is not easily attained and is only accessible to those with God's grace.
