How does Chapter 21 describe the unity and secret arrangement among saints?

Chapter 21 explains that saints, despite appearing in different places and times for specific purposes, are "essentially inseparable from one another." The text uses an analogy, comparing them to outposts established by a sovereign king to maintain order. In this comparison, Sai Baba is the "Emperor of Self-bliss" who invisibly directs the affairs of His kingdom. It is stated that while the country and time may differ, the signs of one saint are completely known to another because, inwardly, they are all one. This points to a secret, divine arrangement that connects all saints.
