According to Chapter 21, what is the relationship between different Saints, and how do they recognize each other?

Chapter 21 explains a profound concept about the unity 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 source clarifies that while their external circumstances like country and time may differ, the signs of one Saint are completely known by another. This is because, as the chapter beautifully puts it, 'Inwardly, they are all one.' This highlights a secret, interconnected arrangement among these great souls, suggesting a universal, unified spiritual consciousness.
